==21224== Your program just tried to execute an instruction that Valgrind
==21224== did not recognise. There are two possible reasons for this.
==21224== 1. Your program has a bug and erroneously jumped to a non-code
==21224== location. If you are running Memcheck and you just saw a
==21224== warning about a bad jump, it's probably your program's fault.
==21224== 2. The instruction is legitimate but Valgrind doesn't handle it,
==21224== i.e. it's Valgrind's fault. If you think this is the case or
==21224== you are not sure, please let us know and we'll try to fix it.
==21224== Either way, Valgrind will now raise a SIGILL signal which will
==21224== probably kill your program.

Hi

Still does not work. This is the readout from the terminal;

Fatal: QWidget: Must construct a QApplication before a QPaintDevice
Aborted (core dumped)

Best of luck

I seem to be having a very similar problem to Angel Guzman Maeso (shakaran). I also ran "valgrind --leak-check=full --show-reachable=yes skype" at the command line, and saw similar errors, ending in a segmentation fault.

The surprising thing is that Skype seemed to run fine under Ubuntu 13.04 Raring Ringtail, but now that I upgraded to 13.10 Saucy Salamander I get the segmentation fault. I'm using a Lenovo S10-3 "ideapad" netbook with a 32-bit CPU. I suppose I'll try downloading the 4.2.0.11-1 version from http://www.skype.com/en/download-skype/skype-for-linux/ .
