freedesktop.org specifications are sometimes ambiguous in their requirements,
leaving room for interpretation. libsfdo tries to follow them as closely as
possible nonetheless, except for cases when doing so would add too much complexity
for no benefit and/or result in suboptimal behavior. Additionally, libsfdo is
much stricter than other implementations, so it may refuse to process non-conformant
desktop entry files or icon themes. It is advised that you try to fix the offending
files before opening an issue.
