I fixed the error.
After figuring out, that glib2.0 had no data to compare the png data to 
in cache_get_mime_type_for_data, I stepped through 
xdg_mime_init_from_directory and discovered only a few data for 
mimetypes were added from my ~/.local/share directory. Stepping through 
the same code on a different computer, most data came from 
/usr/share/mime/mime.cache, but the file was missing on my computer.
Running update-mime-database /usr/share/mime/ as root solved the 
problem. Took me ~7 hours to figure this out ;) Maybe this was the 
result of an upgrade. Because this was when the error occurred the first 
time.
