Bug#1054549: cmus: Segmentation fault when trying to open directory with 444 permission mask

[Krzysztof Aleksander Pyrkosz <krzpyrkosz@gmail.com>]

Package: cmus
Severity: normal

Dear Maintainer,

I've encountered a reporoducible segfault. When trying to enter a directory with 444 permissions owned by root
(lanuch cmus, press "5" to switch to directory selection, and select this
directory) the program segfaults.
