aMule version: 2.2.1 original, not CVS...... bug, as i said, already existed in the previous CVS before 2.2.x was released.

I will compile new CVS from next week on and try to catch more bugs

I hope this helps!!!!!

[GrayFox.i0n]

I was downloading the last OpenSuSe iso and suddenly i decided to cancel the download.
That was the only download in my queue, and something like 10 people was uploading from me that same file.
Suddenly i decided to cancel the download and ... guess what?: Amuleweb crashed again...
This time i didnt do it intentionally, i was not looking for a crash (actually i didnt expected it to crash), and it actually did.

Sorry, no backtrace , but i can intentionally cause the crash anytime i think....
If you think would be any useful, i will make it happen and report the backtrace.....

Cheers!!

Thanks for your reports, they are much appreciated!

Does this only happen when someone is downloading from you or does this happen every time you cancel a download?

Cheers!

Only happens when that file is in use: I.E.: when im sharing it and someone is uploading from it........... while i delete it...

Oh ... that may explain the problem. I see fix already committed.

The fix is not still commited, is it?
I tryed it with today's cvs and still crashes when deleting a file on queue being uploaded in the same time...
