I know ;-)

No it doesn't, actually it only fetches the data, converts it into
char's and puts it into a file. This worked for png-type images. I have
no XPM or XPM.gz at hand to test these, but it should work there too.

So writing out the "raw" data to an xpm.gz produces a broken gzip file?
If not I don't see any need for qUncompress to be used.
