You are right, this is an important bug.
Tracing it down with the debugger, I think it has something to do with the
functions OSRExportToProj4 and OSRImportFromProj4. It seems as if a part of
the last string is still stored somewhere.
The workaround I commited to svn is to delete and recreate the reference
system in QgsSpatialRefSys::operator=
