gksu crashed with SIGSEGV in fputs()

[Dan Wood]

Happened after clicking a launcher (for Spotify) in Unity dock.

(Spotify launched successfully. I don't know why gksu was invoked.)

Could someone please install libc6-dbg package and get a better backtrace?

[Per-Inge (per-inge-hallin)]

I installed libc6-dbg and got a bug which I reported as bug #900268.
I tried to get the bug by starting Spotify, but that went OK.
The crash did not happened in the same place as in bug 899617.

Hope this is of some use.

I installed libc6-dbg, I'm waiting to see if I have the same crash again.
