Bug#958736: supertux: Segfault in Ghouls' lair

Package: supertux
Version: 0.6.1.1-2
Severity: important

Dear Maintainer,

While playing level "Ghouls' Lair", supertux segfaults after a few minutes. The segfaults are not triggered by any obvious user action
or map location.

To try and collect some data I did run `time supertux2` several times,
generating backtraces after each segfault. The result are attached.

Just let me know if I should investigate anything else or should report this upstream (to supertux or mesa).

thanks
Nicola
