Failed assertion in ggsclipper.h

[pmcdermott]

Started QGIS. Opened a project which I had created and worked on before. QGIS crashes with an assertion failure (detail below). Attempting to open the project again results in the same problem.

Do you have the possibility to submit the project and/or offending files?

[pmcdermott]

Sorry, it was some time ago now, so I have completely re-built the offending project

[homann]

I suppose there was an error when changing CRS id numbers from previous versions of QGIS, and this somehow led to a fatal error. I cannot find much of the warning text in teh core, either it has been changed or it comes from a plugin.

I have to set this to worksforme, as we cannot reproduce it.
