Strange batch add behaviour 1.4.2

[xplicit]

Just installed a fresh coppermine gallery for a friend and used version 1.4.2 for it.

But when batch adding the files (221) there are some strange behaviours, all files seems to be seen as double. So i ignored it and just continoued to see what would happen and I got this strange output, notice that some files have the same name (all are seen double) and while batch adding some go OK some DP and also some OK and OK while having the same name.

Seems it got to do with the fact it cant deal so good with the spaces in the file name... ir renames every space by a _

When I try to add files without spaces it all goes well.

Has been taken care of - files that would be identical when spaces get replaced with underscores ("foo_bar.jpg" vs. "foo bar.jpg") now get a ~ postfix. Marking accordingly.
