[Lazarus] Major flaw with trunk and unit cases

[David Emerson]

Reproduced again, and took a screenshot.

I get a standard dialog, "Debugger Exception Notification" for an exception that 
I have raised in my program.

Looking at the call stack, the top line (index 0) shows for the source what 
looks like a memory address; Line 0; function fpc_raiseexception

Then I double-click that line to bring it up in the source window. The source 
window shows binary garbage, and the name of the tab is "saralatools" -- also 
the name of my project folder. The source (garbage) mutates when selecting and 
moving the cursor around.

Stop the debugger, exit lazarus, and SAVE the project-- if I don't save, that 
binary garbage is discarded; if I do save, it replaces my project folder.

Here is a screenshot: http://david9.freepgs.com/i/callstack2.png
I have an unusual color scheme, and usually my source editor has the same 
scheme, but when bringing up this weird thing, it abandons that scheme. You can 
see the selected tab (far right) has a slightly lighter color.
