Sadly, I have no idea exactly how I managed to get such a state of HAL database.
When I try to click on the icon on my desktop which represents the wretched thing
(a Canon camera formatted CF card), exo-eject just crashes in main:
Program received signal SIGSEGV, Segmentation fault.

I managed to work the problem around with the attached patch,
but someone should look into the issue deeper (why is the UDI
listed, for instance? The device is long gone!)
But the patch should be applied anyway: it is no good to try to
report an error which is not described properly (the GError *err
is never set when that err0 branch is taken. Not to mention
suspicious use of goto here: _inside_ a conditional _past_ exactly
that err != NULL check?!)
