First of all, I'd like to say hi to everyone in this forum an greet to aMule team for their great work.

I have updated aMule Packman package with Apper in my OpenSuSE 12.1 x86_64 + KDE4.9 PC and now amule gui chrashes at startup after saving part files.

Sometimes it closes the gui and other times the gui remains unresponsive after the crash.

This computer had previous aMule Packman package version (2.3.1 as well) working when it was upgraded from OpenSuSE 12.0 x86_64 + KD4.7 to OpenSuSE 12.1 x86_64 + KD4.7 and then to OpenSuSE 12.1 x86_64 + KD4.9.

Crashes began immediately after upgrading aMule Packman package.

When I run amule from console with my user (no problem before upgrading package) I get this log (only showing final part of it):

I have  aMule Packman package running in my laptop fresh installed with OpenSuSE 12.1 x86_64 + KDE4.7 and sometime later  upgraded to OpenSuSE 12.1 x86_64 + KDE4.9. I have updated aMule Packman package via Apper in my OpenSuSE 12.1 x86_64 + KDE4.9 and it works perfect in my laptop.

Could anyone point me what library/program is causing this crashes or give any hint on how to solve this problem?

Thanks in advance.

I'd suspect something fishy with the wxWidgets that is part of that distro.
What I'm wondering is why aMule is saving partfiles on startup. Is it terminating right after start and then crashing on shutdown? What is it doing before saving the partfiles?

[Xnake]

I've removed any libwx* package no other program depends on, and the behaviour it's the same. I've even tried a different package (different version number) from another OpenSuSE repository, with same errors.

When I run amule command on a terminal, the log now is (translated from Spanish):

After aMule loads the part files, it shows the GUI. When adds them to shared files I can see all the files in the download tab, but the GUI is unresponsive.

I tried compiling aMule from source code, but when I run ./configure --disable-debug --enable-optimize it cant't find wx-config because there is no such wx-config (I've searched for it in all my partitions).

I think it has something to do wiht wxWidgets too, so I'll wait for a new aMule Packman package or I'll upgrade to OpenSuSE 12.2 on September, 4th. If still I can't get the problem solved, I'll save my data and I'll run an OpenSuSE 12.2 fresh install.

Thank you very much for the answer.

I finally sorted my problem out! 

It was caused by connecting to eDonkeyServer No2 (212.63.206.35). AMAZING! 

I got lucky when I had aMule running smoothly in my laptop, connected to another server, and when I tried to connect to that server aMule crashed.

I downloaded a fresh server.met and aMule runs perfect now in my PC. I checked my theory connecting to that "bad" server and aMule hangs/crashes. Why? I have no idea. I've deleted that server from my server list.

Thanks for your help!

[Stu Redman]

Now this is interesting.

I've just tried this server too and had no problems. I don't have that many active downloads though.
Maybe something breaks there when it transfers you huge file list or something.

Anyway good to hear you got it running at last!

Hi all,
I've the same problem reported by Xnake.
I'm on a OpenSUSE 12.1 x86 and aMule version is 2.3.1: the crash report (without backtrace) is the same of Xnake.
I tried to investigate the crash, and I understood that's related both to the ed2k network and the other clients. Many times, but not always, when I connect to a server (ed2k) aMule crash; also crashes everytime when I'm downloading something and I click on the download: I think that crashes when tries to show the clients details. AMule seems to work properly IF:
1) I don't connect to the ed2k network
2) I don't click any download (I didn't tried on uploads)
I'm available to carry out further tests

Thanks for your support
