[STUMP] UTF8 related bug

[Stefan Reichör]

Because I have learned today where to look up a crash in stumpwm, I have
another crash that happens from time to time.

When I open a file containing an umlaut (e.g. ö) in evince, the whole
stumpwm session dies with the following backtrace:


Caught '
CONVERT-STRING-FROM-BYTES: Invalid byte sequence #xF6 #x72 #x2E #x70 in 
CHARSET:UTF-8 conversion
