Application: kdevelop (4.2.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.2.2-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I opened kdevelop over an SSH X11 tunnel to browse some code.  No edits were made.  It sat open and idle after that for several hours.  I hit Ctrl-Q to close kdevelop, and it crashed.

Odd behavior noted previously: kdevelop over SSH X11 tunneling is often very very very slow.  Other KDE applications (kompare, konsole, etc) are OK over the same connection, as are non-KDE applications such as Firefox and Thunderbird.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
