Could you somehow have QT_NO_CAST_ASCII defined while building? Looking in
qstring.h, it should be using this operator+ on line 1050:
inline const QString operator+( const char *s1, const QString &s2 )
Your build doesn't appear to be finding that, though. Since the definition is
wrapped in a #ifndef QT_NO_CAST_ASCII, it seems like having that defined
while building could cause your build failure.
...
A quick grep -r through the kdenetwork sources shows that this appears to be
defined in all the kopete Makefile.am's and Makefile.in's, but not in any
other kdenetwork packages. So, I wonder how the buildd's built it?
