Here is the backtrace.

Program received signal SIGSEGV, Segmentation fault.
0x40a3c414 in QDBusAbstractInterface::isValid() const () from
/opt/qtmoko/lib/libQtDBus.so.4
(gdb) where
#0  0x40a3c414 in QDBusAbstractInterface::isValid() const () from

Backtrace stopped: previous frame identical to this frame (corrupt stack?)


Any suggestion to restore functional qtMoko is welcome.
