Indeed!

... Or, depending on your "application formerly known as kcontrol, 
generically aka system settings", settings (got that, the kcontrol aka 
systemsettings settings, even if it doesn't really control many system 
settings at all, see that sysconfig setting mentioned above, it's for kde 
settings, thus kcontrol is more accurate in any case), under "Advanced 
User Settings", "File Associations".  That's on kde 4.3.3, kcontrol set 
to "classic tree view".

Under file associations, under inode, I'd check blockdev, directory, and 
mount-point.  Were it a CD/DVD, I'd also check under x-content for the 
appropriate media type, but unless you've done something exotic like 
format your USB mass-storage as ISO-9660 or some such, that's unlikely to 
be of interest, here.

Another place to check, also under advanced user settings, is Device 
Actions.  That's based on info hal feeds in, with each action available 
or not based on a boolean logic tree.  The open with filemanager action 
should be there.  Here, it's set to "kioclient exec %f".

So now we lookup kioclient.  Try running kioclient --help in a konsole 
window.  Here, the interesting option for further information is 
kioclient --commands.  Running that and checking the exec option, the
"%f" above would be a placeholder for the file (likely presented as a 
file:// url), aka the 'url' in the documentation.  'mimetype' is omitted, 
so according to that, the mimetype is determined automatically (by file 
associations).

Which brings us back to file associations, but there's another angle on 
them other than the one above.  Above, we checked the logical mimetypes 
to see if they had any strange OOo associated actions, but the reverse 
possibility is that the normal OOo mimetype is for some reason too broad, 
and taking in whole filesystems or block devices (presumably fat32 if 
you've not formatted the mass-storage otherwise).  So that's the other 
thing to check there.  Do a search for openoffic.org-2-2 and see what 
comes up.

Also note that it's possible, particularly if you upgraded in-place, that 
the setting might be in the system mimetypes, not your user mimetypes.  
One way to check that would be (from a VT with X not running, or from 
Gnome or something other than kde4, at least) to rename your ~/.kde4 dir 
temporarily, then log back in with a "clean" user config, and see if the 
action happens then.  If it does, it's very likely a system config 
issue.  If not, you know it's in your user kde config.  You can of course 
revert the temporary test at that point, again logged out of KDE, of 
course, deleting the temp config it wrote during the test and replacing 
it with your original config, if desired.  If you have as many 
customizations as I do, you'll desire.  If you don't customize much, 
it'll probably be no big deal to blow away the old config and start anew, 
and simpler to do that than to find the issue.

Another testing alternative, even more thorough, would be to create a 
brand new user, entirely fresh home dir, and login to kde as them.  If 
the problem exists there, you know for sure it's a system problem, since 
there was no existing user config at all to even consider.  If it 
doesn't, you know it's a user config problem.
