Hi!

I am getting some weird crashes on solaris x86. I am using the above mentioned SVN version and wxGTK 2.8.4. Here is the backtrace, I got it while trying to get a new serverlist (aMule was just starting, with no .aMule folder at all). I split the whole output into the different command output I gave (bt, bt full etc) but other than that, it's exactly what it threw at me:

Looks like it crashes inside WX, somewhere in HTTPDownload

[skolnick]

I'll try to build the latest wx2.8.7 and report back, maybe it's a bug on their side.

Thanks!

[skolnick]

I rebuilt everything and the crash is not happening anymore. The problem seems to be related to build wxGTK linked to GNU libiconv. I rebuilt it using native solaris iconv and now it doesn't crash anymore.

Regards.
