[Bug 287312] [NEW] ark not working properly with gzipped files

[Harald Sitter]

Public bug reported:

Binary package hint: kdeutils

For kdeutils 4:4.1.2-0ubuntu5
<slangasek> apachelogger: why are there no bugs referenced in this kdeutils upload?
<apachelogger> slangasek: I didn't find one, ScottK however complained about gz files not being opened properly, I can explain the problem if you want
<slangasek> apachelogger: explain it in a bug and subscribe ubuntu-release, please

The patch kubuntu_03_add_ark_gzplugin.diff  (as introduced in
4:4.1.2-0ubuntu4) was insufficient. Whenever ark opens a file it queries
the KDE cache for KServices (applications/plugins/similar stuff) with
the file's mimetype, in order to find the most appropriate backend for
it. The way Ark queries the cache leads to a first hit result, in some
cases this would be the libarchive backend (which is listing
application/x-gzip, even though it doesn't support this mimetype at
all). Now, in order to make Ark use the libgz backend (which can handle
the affected mimetype), the application/x-gzip mimetype needs to be
removed from the libarchive backend's desktop file.

Result of the change: Ark opens gzipped files properly

Danger: None. Libarchive doesn't process application/x-gzip properly in
any case, forcing Ark to get libgz as a result for the backend query is
only an improvement.
