Can't profile KDevelop with callgrind with QtHelp doc plugin enabled

Sun Apr 4 16:50:41 UTC 2010

Hey, I just wonder whether I'm the only one who can't profile KDevelop when 
QtHelp is loaded. Callgrind crashes for some reason during loading. See 
attachment for details.

Does anyone know what's the problem?

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.
