Comment 1 Andrea Diamantini 2011-03-19 09:50:19 UTC 
Sorry, I don't see *ANY* rekonq code in your bt as the usual event loop. And your situation is something NOT happening in any other one system that I'm aware running rekonq.
So, I guess this is your system problem. Try upgrading to Qt 4.7.2 and to the latest rekonq (actually, 0.6.89) removing also the config file (that is in $KDEHOME/share/config/rekonqrc).
Comment 2 Landon M. Kelsey, III 2011-07-09 19:50:23 UTC 
I only get this crash about 90% of the time.

It makes Fedora 15 practically useless!

Luckily I have dual boot and can use XP Prof SP3

May have something to do with windows open when the last session was closed.
Comment 3 Landon M. Kelsey, III 2011-07-09 20:40:53 UTC 
did yum update and now have qt 4.7.3

got crash twice in a row

I had to push the reset button on the computer to reboot

I am using latest Firefox which remained after crash
Comment 4 Landon M. Kelsey, III 2011-07-09 20:48:15 UTC 
I did a yum update and now have qt 4.7.3.

reboot...got 2 crashes in a row

Executable: knotify4 PID: 2616 Signal: Segmentation fault (11)

GREAT reason to maintain dual boot...sure glad I am NOT a newbie
Comment 5 Landon M. Kelsey, III 2011-07-09 21:05:15 UTC 
may have fixed problem

(1) yum update
(2) reboot

Comment 6 Landon M. Kelsey, III 2011-07-09 22:20:19 UTC 
(1) could not find $KDEHOME/share/config/rekonqrc

(2) locate rekonqrc showed no hits
Comment 7 Landon M. Kelsey, III 2011-07-09 23:38:13 UTC 
yum update....reboot seems to have worked
Comment 8 Landon M. Kelsey, III 2011-07-10 04:49:34 UTC 
yum update....reboot seems to have worked...execpt now the rate of crash is lower

1 out of 10 instead of 5 out of 6
Comment 9 Landon M. Kelsey, III 2011-07-13 00:44:16 UTC 
new kernel from yum update:
2.6.38.8-35.fc15.i686

then 2 crashes in a row

KSMServer PID  1836
Comment 10 Landon M. Kelsey, III 2011-07-20 04:35:00 UTC 
no more crashes after yum update ...thanks!

now have 4.6.5

$ kde4-config -v
Qt: 4.7.3
KDE Development Platform: 4.6.5 (4.6.5)
