Dolphin browser will occasionally freeze

I notice this especially in the usb flash drive, when i put my mouse over a pdf file with many pages (over 9mb in size)

edit: i can confirm this also happens in other places besides the flash drive area. When i put my mouse over a large pdf file it dolphin will hang up for around 3 to 5 seconds.

Also gota fatal error

A Fatal Error Occurred
The application Dolphin (dolphin) crashed and caused the signal 11 (SIGSEGV).
Please help us improve the software you use by filing a report at http://bugs.kde.org. Useful details include how to reproduce the error, documents that were loaded, etc.

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

Anyone know?

out of curiosity which version of kde and dolphin are you using? i used to see the same behavior in kde4.0 but haven’t seen it since switching to kde4.1

Im using kde 4.2.2 and dolphin 1.2.1

I wish I could help, I’ve seen this behavior in 4.1 and 4.2 when I try to open a video in my windows partition or a .mp4 file anywhere. Dolphin would become unresponsive for about 15 seconds then it would work normally. I haven’t had the problem in 4.3 yet (knock on wood).

Here’s the bug report https://bugs.kde.org/show_bug.cgi?id=163050
