I had a bit of a look at the other uninspected cases. I did not make any
changes in the web interface though.

Probably not wrong, but IMO at least a case of bad/obfuscated coding.

CID37
At least the analysis is completely off. I also think there probably is
no resource leak at all here, but I did not check in detail.

CID44
I think this issue might actually cause crashes and not just a leak.
Without knowing the code well enough, the whole function looks a bit fishy
to me.

The CID49 one I think is fixed in SVN.

CID56
Seems completely bogus to me. I have seen the tool mess up completely a
few times in such cases before.

CID72
Seems already fixed in SVN.
