No replies yet on this thread.... no one faced a similar
issue while doing a periodic RPM upgrade?
I've dug some more into this issue and found another thread
which may be related to my problems, but no answers to that
thread as well.
Read up the shared-mime-info spec and some other posts on
the gnomesupport.org site. With that I could make out that
I needed to export XDG_DATA_DIRS for some progress. I did
so in my .bashrc and .bash_profile (I guess I need have put
it in only one of them ideally, but anyways).
After that my nautilus is showing PDF thumbnails (which it
was not earlier, so that's a nice discovery ;) but the file
associations are still not working (!?!??)
Now, shared-mime-info spec says that it does not tell which
application should be preferred to open which MIME type. It
may at most give a list of applications that 'can open' this
MIME type. So, where does the preference information reside??
Should I export some other environment variables (XDG_DATA_HOME
and so on) and if so, where? Or am I missing some package
that I need to install?
To repeat, my problems currently are:
* Help files open in gedit even if I run yelp from
the terminal after exporting the XDG_DATA_DIRS variable.
* No file association works on its own and double-clicking
any file-type in nautilus just shows an error popup with the
"no action associated" text.
Any help will be most welcome! :)
