Description of problem:

On updating blender get the following messages:

Unknown media type in type 'all/all'
Unknown media type in type 'all/allfiles'
Unknown media type in type 'uri/mms'
Unknown media type in type 'uri/mmst'
Unknown media type in type 'uri/mmsu'
Unknown media type in type 'uri/pnm'
Unknown media type in type 'uri/rtspt'
Unknown media type in type 'uri/rtspu'
Error in file "/usr/share/applications/qtractor.desktop": "" is an invalid MIME type ("" does not contain a subtype)


Version-Release number of selected component (if applicable):
qtractor-0.5.8-1.fc19.x86_64

How reproducible:
Probably just running update-mime-database should do it.

Steps to Reproduce:
1. Install qtractor
2. Update/install blender
3. 
  
Actual results:
Get above errors/warnings

Expected results:
No errors/warnings

Additional info:
Seems that the error about qtractor.desktop is due to extra semicolon in the mimetype:

MimeType=application/x-qtractor-session;application/x-qtractor-template;application/x-qtractor-archive;;

Looking at the sources original qtractor.desktop.in seems ok, extra semicolon actually is added by sed in %prep step:

%prep
%setup -q -n %{name}-%{version}
%patch1 -p1
%patch2 -p1
sed -i -e 's|archive|archive;|' src/qtractor.desktop.in

Removing should rid the error.
