jockey-kde crashes with SIGSEGV on exit

[dn]

When I click the X button on jockey-kde, a program called "The KDE Crash Handler" (drkonqi?) shows up with a backtrace saying it crashed.

Reproducible: Always

The .kcrash file it generated read:
---------------------------------------------------------------------
Application: Jockey (), signal SIGSEGV
