Comment 5 Jacob 2003-11-20 06:34:21 UTC 
I just had this bug trigger as described in bug 67965, only this time, klipper
was not running.  Therefore klipper is not required, but it does make the bug
much easier to reproduce.

Comment 7 Ingo Klöcker 2003-12-08 01:21:29 UTC 
I can trigger this bug 100% reproducible by dragging a local file from the History/Miscellaneous in the Navigation Panel to another Konqueror instance.
Comment 8 markus 2003-12-11 11:29:29 UTC 
its really a bad bug. no crash dialog. gets me to kde3.1.3 again. because slack uses qt 3.1.2 then. qt 3.2* causes konqueror to stop without saying something :)
cvs kde 3.2 (beta2) has this too. cant wait to see it fixed. qt people say its a kde bug. kde says its qt bug ;)
Comment 9 Lubos Lunak 2003-12-11 12:55:12 UTC 
'qt people say its a kde bug'
Huh? It _cannot_ be KDE bug. Could you please provide me with the mails or whatever with details about this (to my mail)?

Comment 13 Ingo Klöcker 2004-01-19 22:18:06 UTC 
I also just experienced this crash (using qt-copy from before Qt 3.3 Beta 1 was committed). I had just sent a message with KMail when a Konqueror window which was showing one of my bugs.kde.org queries crashed. I didn't do anything with this window, but it's possible that this window got the focus after the message composer window was closed.

The backtrace:

Comment 20 Tuomas Suutari 2004-01-26 22:35:49 UTC 
I tried this patch too. And it did the trick. =)

Previously my Konqueror was silently killed, if I switched from another desktop to Konquerors one. If Konquerors location field was selected, Konqueror just disappeared. But not anymore.

Nice work. Thanks.

btw. Version of qt I applied the patch to was Gentoo's qt-3.2.3-r1.

It's working fine here after applying the patch to Gentoo's qt-3.3.0-r1.

Thx for fixing it :)

Comment 39 Ernst de Haan 2004-04-03 18:08:12 UTC 
Same here, with KDE 3.2.1 (compiled from sources), on FreeBSD 4.9-STABLE.

Message I get is:
QClipboard: internal error, qt_xclb_wait_for_event recursed

Comment 45 Eduardo Robles Elvira 2004-05-25 17:38:23 UTC 
I'm using KDE 3.2.2, and I get the same error *sometimes* (i.e. not always, and rather randmly) when I drag an image from konqueror to KDE desktop:

QClipboard: internal error, qt_xclb_wait_for_event recursed

Kdesktop crashes and closes: icons dissapear from the desktop et all. Execting kdesktop fo course gives me back the desktop icons and the remaining kdesktop things.
Comment 46 Eduardo Robles Elvira 2004-05-31 10:35:15 UTC 
It has happened one more time, with a different behaviour:

The "QClipboard: internal error, qt_xclb_wait_for_event recursed" error appeared once more to me doing normal file managing tasks with konqueror (KDE 3.2.2). This time I had lockups and crashes of many apps. My whole desktop (even Mozilla Firefox 0.8! ?) became really inestable and I had to close sesion. Restarting session solved the temporal problem.

However, I  haven't managed to reproduce the bug, and no valid backtrace was ever given. Anyone has an idea about what happened?

does upgrading Qt to 3.3 or qtcopy:HEAD is a good idea ?
