Description of problem: I think HelixPlayer probably needs to run update-mime-database or update-desktop-database (or both) in %post and %postun, like gimp, eog and file-roller do. Version-Release number of selected component (if applicable): 1.0.gold-3
update-desktop-database isn't useful until HelixPlayer actually uses the new MIME system (which is the real bug here :/). I have the call to u-d-d in CVS, but it's pending on upstream response to the MIME setup.
This bug is upstream here: https://bugs.helixcommunity.org/show_bug.cgi?id=3101 Keeping it open here so it's visible on my list of things to fix.
Can we just patch their .desktop file as a short term fix?
Hmm...actually this seems to be done now. I guess upstream has had the MimeType and I missed it somehow? Anyways, it works for me, closing.
Actually I forgot, the main bug here is that the player seems to not process commandline arguments correctly.
This was a bug in the spec file.
