synaptic package manager does't start anymore

Asked by Horst Seeger on 2011-10-18

After upgrade to ubuntu 11.10 first synaptic worked normal. Then it started to flash only without starting. When I tried to start through terminal I got this error message:

(gksudo:16652): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",
terminate called after throwing an instance of 'std::out_of_range'
  what(): vector::_M_range_check

What is the problem and how to solve it?

Should cure the warning.
See post #7
Seems to fix it.

I got answer, that it is installed already

but switching off "visual alerts" in Universal Access (post n° 7) has cured it. Thanks!
