[JYA]

Fresh, new, blank system as per #10925. Create new mythconverg database run mythtv-setup and create a basic system (capture card, etc..) run mythbackend

start mythfrontend it prompts you to choose your language. Save and mythfrontend now hangs.

It is deadlocked

void MythPainter::DeleteFormatImage(MythImage *im)
{
    m_allocationLock.lock();
    DeleteFormatImagePriv(im);

on m_allocationLock.lock();
