Description Andreas 2012-01-08 15:16:00 UTC

Version:           unspecified (using KDE 4.7.4) 
OS:                Linux

I use konqueror 4.7.4 on KDE 4.7.4 on kubuntu 10.11. It gets sometimes (too often) stuck for several seconds if I e.g. right click a link on a webpage, if I want to switch to a different tab by clicking it or if I try to scroll. In each case it freezes before the requested action is taken (show right click menu, show the other tab, scroll). There is usally no crash involved. After a while I can usually continue browsing. http://code.google.com/p/n2hell/ is not installed as in Bug 203170 .

Reproducible: Sometimes

Steps to Reproduce:
Unfortunately I cannot give any recipe to reproduce the bug as it seems to occur randomly (different webpages, different links etc). 


Expected Results:  
Normal operation without interruptions.

I should add that it can also happen with simple single clicks on links and that the CPU usage stays low. I had a similar prolem with older versions of kde 4.7 but it disappeared after I installed various ubuntu bugfixes. Also I had error messages in .xsession_errors which I could relate to konqueror. Btw. I am using konqueror with webkit but do not know whether it makes a difference.

what version of kwebkitpart is installed on your system ? Which version of Qt ? Since you are using the webkit browser engine, this issue has nothing in common with bug 203170 as that concerns the khtml engine.

Comment 3 Andreas 2012-01-09 08:51:44 UTC

kpart-webkit: 0.9.6-0ubuntu3
qt: 4.7.4
Since the latest updates I experience also problems with krunner and system notifications in addition to the problem described above. Could it be a plasma or akonadi issue?

Comment 4 Andreas 2012-01-09 11:31:43 UTC

I confirmed that the problem actually exists also with khtml part.

Comment 5 Andreas 2012-01-19 15:43:45 UTC

It seems that the problem was related to old nspluginviewer/flash problems. It seems it was solved by manual installation of the current flash 11.2 beta. Should the Ubuntu flash installation packages be updated.
