Bug 242668

Application: kdevelop (4.0.0 (using KDevPlatform 1.0.0))
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.2
Operating System: Linux 2.6.33.5-112.fc13.x86_64 x86_64
Distribution: "Fedora release 13 (Goddard)"

-- Information about the crash:
After using KDevelop for a while, I selected Session/Quit.  KDevelop crashed.

There are a bunch of similar bugs where glibc detects malloc/free problems.  Here the last call before entering glibc is QString::free().  The other bugs (I've noted a few possible duplicates) have different stack traces, but perhaps they have the same root cause.

 -- Backtrace:
Application: KDevelop (kdevelop.bin), signal: Aborted
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
