I checked the repository for an update, and it still has no typeinfo for QPlainTextEdit. However, perhaps a seemingly insignificant modification I made in my code (e.g. changing a dynamic_cast to a static_cast) fixed the problem.

This helped me a lot. I was able to fix the problem.
Before I was not aware, that the symbol files for Qt are in the contrib directory and so I didn't search there for them.
I have created an issue in cproc's repository and pushed the fix to my clone of it.
