Hi, just pointing out.

lxsession-edit has a string that doesn't show translated because it ends with a trailing space. There's a bug report for it at https://sourceforge.net/tracker/?func=detail&aid=3303991&group_id=180858&atid=894869

gpicview also has two strings that don't show translated because (I suppose) they end with a tab space ('slideshow interval' and 'sec').

pcmanfm/libfm also has some strings that aren't translated but these probably aren't marked as translated as they aren't present in the pot files.

'Filesystem' may be coming from libfm/src/udisks/g-udisks-volume.c (?)
