Description Jyot 2009-08-18 20:30:49 UTC 
Version:           0.8.1 (using KDE 4.3.0)
OS:                Linux
Installed from:    Ubuntu Packages

this is what it asked me to report. I don't have much knowledge on it.. noob to linux. Anyways, love it. I took about 8 snapshots and then it crashed. I had mozilla and amorock on. Nothing else.

Application: KSnapshot (ksnapshot), signal SIGSEGV
