[wuischke]

Please report this issue to the Ubuntu developers, too. It's most probably related to X11 or gtk, maybe they know more about it.

[jpv950]

I would but I don't think they'll accept a bug against amule's development branch.

[wuischke]

Please do so nonetheless and include a link in this thread.

There are related reports (for instance https://bugs.launchpad.net/ubuntu/+source/libxcb/+bug/259708 ;just google "../../src/xcb_lock.c:33: _XCBUnlockDisplay: Assertion `xcb_get_request_sent(dpy->xcb->connection) == dpy->request' failed.") in the Ubuntu bug tracker. I hope the Ubuntu developers might know what's causing this bug and what might be done to resolve the problem.

Thank you for your collaboration!

[btkaos]

It would be extremely helpful if you could install all the debug packages and try to reproduce the bug. (And please build aMule and wx with debug support)

The packages in questions are (in x86 ubuntu) libc-dbg libx11-6-dbg libx11-xcb1-dbg libwxbase2.8-dbg libwxgtk2.8-dbg libgtk2.0-0-dbg

[BTW, this should go in the FAQ for reporting bugs]

[jpv950]

I have built WxWidgets and aMule with debug support. I was missing some debug packages but they are installed now. I'll try to reproduce the bug and post the backtrace in launchpad then.

Like wuischke said, this is probably a bug in libxcb.

[jpv950]

Different crash, using rev9371 on Ubuntu Jaunty alpha 3 x64.
