Crash of the visual basic 6 IDE just before loading the project ends; only when source safe is active

I am at my wits end with this one. I have a vb6 project that edits, compiles and runs well as long as I do not t开发者_如何学运维ry to synchronize its files with the visual source safe 6.0d database at loading. I tried removing the .scc files, I tried filling the working folder from the database and vice versa, all to no avail.

The problem started when I tried to add a new class module to the project, for which VB6 complained that the .vbp project file should be checked out first. Somewhere after that I got an error and now this is the result.

What file could be the culprit in such a way that it does not interfere with 'source safe-less' execution, but causes a crash when I do use it???

I have been unable to reliably reproduce the error, but it seems to happen when the number of files in the project reaches a certain level. A workaround I found is to disable sourcecontrol before loading the project and loading the sourcecontrol AddIn after all files are present in the IDE.
