Description Mathias Panzenböck 2010-04-08 20:37:23 UTC 
Application: rekonq (0.4.59)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.10-90.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
I use current git of rekonq: 43dc2695d62fd2e4fc01aff608bb2af3e8335040 (Thu Apr 8 02:53:38 2010 +0200)

I tested rekonq by opening a LOT of galleries and images on deviantart.com and one youtube video. The good news: rekonq seems to scale much better than firefox. There is no noticable decrease in performance when opening a lot of tabs.
The bad news: deviantArts JavaScript is very buggy with rekonq (dragging images to your favourites, middle-clicking images in the gallery seems not to raise a mouse-up event). And when I closed the browser window (with all tabs still open) rekonq crashed.

 -- Backtrace:
Application: rekonq (rekonq), signal: Aborted
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)

Comment 1 Dario Andres 2010-04-09 14:41:57 UTC 
This looks like bug 196207... do you get this crash all the times you repeat the same situation ? If you do, there is a test to perform...
Regards
Comment 2 Mathias Panzenböck 2010-04-09 15:00:47 UTC 
Using several devinatArt and one YouTube tab I couldn't reproduce the crash.

How could this be related to bug 196207? That bug seems to be about gtk apps, which rekonq isn't.
Comment 3 Dario Andres 2010-04-09 15:05:33 UTC 
<offtopic>The description of that other bug is not really the best... it is a cause related to multithreading apps using glib (one of the gtk pillars), causing a crash on free(). As Qt use glib (to be able to integrate with other gtk plugins), some applications are affected if you have the affected glib version)
The backtrace seems to match, so the crash could be related, or not, that is why we need to test...</offtopic>
Comment 4 Andrea Diamantini 2010-05-14 01:51:45 UTC 
I really cannot reproduce this, sorry. I'll move to a worksforme if no news will arrive here in a couple of days..
