exception is thrown instead.

Please provide any additional information below.

Does it always happen or is it only one video?

If you know C# / Visual studio you can debug it... otherwise you can try this: 
http://www.nikse.dk/SubtitleEditDebug.zip (exe file only)
(should also display a line number when/if it crashes)

I tested it on 2 other files and it didn't throw any error.
I happen to know C# and compiled the project myself. Guess what, no exception! 
So it's only thrown in the build I downloaded?

I might have fixed the error... did you download latest version in svn or the 
zip source file from "SE 3.3.4 C# source code" ?

I downloaded the zip-file.
Can you explain what the error was, I'm interested. Is the source different 
from the source which the .exe is compiled for, since I didn't get the error on 
the compiled version.

No, the source code you got and SE 3.3.4 should be the same!

Latest version in SVN has many changes though: 
http://code.google.com/p/subtitleedit/source/checkout
compiled http://www.nikse.dk/SubtitleEdit.zip

That compiled version works, so It's solved I guess. Weird I didn't got the 
error when I compiled it myself though.

Yes, weird as the SE 3.3.4 and the 3.3.4 source should be the same.
Unless you downloaded a 3.3.4 version from nikse.dk? (beta/test versions)

Well, I guess I'll close this for now
