-- Information about the crash:
Attempted to open a large cachegrind file (I later looked at the size: 2.5Gb). "Loading..." progress bar chugs along nicely for a while, then the app dies with a segfault.

The crash can be reproduced every time.

 -- Backtrace:
Application: KCachegrind (kcachegrind), signal: Segmentation fault
