New crash information added by DrKonqi

konsole (2.7.999) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

same file, bzcat instead of cat (still binary because it's a tar file)

the file that catted made konsole crash

Comment 4 Jekyll Wu 2011-10-24 13:43:50 UTC

Thanks for reporting. This is actually a known problem and already tracked in bug #184964. 

The trouble is it is not reproducible in the sense of for every time and for every one. For example, the attached file doesn't crash konsole for me no matter how many times I try to cat or bzcat it.
