Comment 2 Petr Dvorak 2008-03-12 14:09:32 UTC
As I am getting the message quite regularly whenever the Diff window appears, the priority of this issue should be raised to P2. Diff is a commonly used tool 
when working with VCS.
Comment 3 Tomas Stupka 2008-03-12 14:56:00 UTC
could reproduce only on mac

however, p3 as the diff seems to work fine, it's just that the exception is thrown.

reassigning to editor for further evaluation

Comment 4 Jan Becicka 2008-03-26 13:16:34 UTC
Milo, please evaluate. Thanks
Comment 5 Vitezslav Stejskal 2008-03-26 14:38:16 UTC
The exception is harmless, in the worst case scenario some folds might be missing. Also, CustomFoldManager should stop
using old Syntax and start using lexer. I think I rewrote this a long time ago when experimenting with isolating Syntax
to a deprecated autoload module. The code should still be on some branch in CVS, so I'll try to dig it out and apply it
to the current codebase.
Comment 6 Miloslav Metelka 2008-03-26 15:13:44 UTC
I was able to reproduce in the recent dev builds. It's just enough to remove the initial comment in any versioned source
and invoke the diff tool.
Comment 7 Jiri Prox 2008-04-11 00:41:37 UTC
moving opened issues from TM <= 6.1 to TM=Dev
Comment 8 Vitezslav Stejskal 2008-06-26 14:26:56 UTC
It seems to be working fine in a dev build. Plus the CustomFoldManager has recently been updated to use lexer tokens and
the stacktrace no longer applies. Please reopen if this is still a problem.
Comment 9 Petr Dvorak 2008-09-17 12:53:56 UTC
Yes, it is very likely fixed. Verified.
