Linux: segfault when closing the Launcher window

[jfinkhaeuser]

Close the launcher window via the (x) button (window decoration), and it crashes if any tasklets have been started and stopped:

Program received signal SIGSEGV, Segmentation fault.

Same happens if you start the Launcher, start a tasklet, close the Launcher window, and then close the tasklet window.

[jfinkhaeuser]

Actually, the same happens whenever you close the last window it seems.

It might be worth noting that I've got tasklets in the launcher list, but none of them are running. Start launcher, stop launcher, crash.

Nope, even when I delete the preferences. It seems this is nicely reproducible at least.
