Description Pascal S. de Kloe 2006-09-19 16:24:33 UTC

Version:           0.12.2 (using KDE KDE 3.5.4)
Installed from:    Ubuntu Packages

Kopete can't handle a large amount of Nudges. Someone with a fast finger can lock Kopete within 12 seconds on a dual Xeon 2.4GHz.
The window becomes unresponsive and the CPU usage goes up to a 100%. Kopete does not restore.

This problem was tested with MSN.

If it crashes, do you have a backtrace?

Comment 2 Pascal S. de Kloe 2006-11-10 07:53:33 UTC

It doesn't crash. Just try it and you'll see.

Comment 3 Philip Rodrigues 2006-11-10 19:14:21 UTC

Retitling to reflect comment 2. Matt, do you use severity 'crash' for freeze-type bugs in kopete, or just 'normal'?

Comment 4 Matt Rogers 2006-11-10 23:09:05 UTC

normal. :)

Comment 6 Ruud Koolen 2008-07-07 15:36:51 UTC

Confirmed in kde4 (Kopete 0.50.80).

Comment 7 Ruud Koolen 2008-07-07 15:44:30 UTC

This is probably a bug in the "Kopete" chat window style, as the "Clear" style doesn't have this problem. The "Kopete" style seems to nest nudges in consecutive tables or something along those lines (each nudge is slightly narrower than the previous), which undoubtedly slows down khtml.

Comment 8 Salvo "LtWorf" Tomaselli 2008-07-09 15:42:40 UTC

In my case it was likely due to several notifications handled by knotify.
The easiest solution would be store a timestamp of the last nudge and show the new one only if the previous is more than 3 second old.

We've completely replaced the current MSN implementation with a new MSN implementation which  If you continue to experience this bug after testing the new implementation (which can be gotten from our subversion repository or with the KDE 4.2 Beta 1 release), PLEASE, open a new bug rather than reopening this bug. Thank you for your time and efforting in helping us find and fix problems in Kopete.
