Exception when parsing some desktop files

[Philipp Wolfer]

Earycandy has problems with some .desktop files where there are several commands in Exec separated by semicolons. E.g. on my system there is the file ~/.local/share/applications/gthumb-import.desktop which includes the following Exec line:
Exec=sh -c 'gvfs-mount -u "%U"; exec gthumb --import-photos'

Obviously ConfigParser returns such values not as a string but as a list. I have a fix in my branch at http://bazaar.launchpad.net/~phw/earcandy/fixes/revision/81 .

Without the fix the following exeption is thrown when scanning such a .desktop file:

TypeError: expected string or buffer
