To demonstrate that the problem is real:

Attached is a screenshot. Remark that the same files are opened twice.

How did I get there ? Simple:

I have /home/michael/FPC/trunk as my copy of FPC trunk.

I have a symlink /home/michael/fpc pointing to the trunk directory.

I opened a project /home/michael/fpc/utils/pas2js/pas2js.lpr (used the symlink), 
with all files in /home/michael/fpc/packages/fcl-js/src opened in the ide. 
I put a breakpoint in jsparser.pp.

I hit run, and when hitting the breakpoints, Lazarus opens the source files AGAIN,
but now with base path /home/michael/FPC/trunk, and appends a (2) after the filename.

Extremely annoying, and since I do a lot of work in trunk, I stopped using the 
symlinked directories when opening files.

Just to show that this is not some freak occurrence, but a major PITA.

Michael.
