Comment 2 for bug 1226030

That's actually what the ui.test_run_crash_precollected test case should cover. Could it be that there is no gdb installed on the phone, so that it cannot actually determine a StacktraceAddressSignature and Stacktrace? The dependency was removed from apport itself a long time ago due to

apport (1.8.1-0ubuntu1) karmic; urgency=low

  * Move gdb dependency from apport to GUI packages to avoid pulling in gdb on
    Ubuntu server. Thanks to Steve Beattie! (LP: #354172)

But indeed these days apport cannot work any more without gdb, so I think I'll just add it back. Subscribing Steve Beattie.

JB, could you try installing gdb on the phone and verify that this works then? Thanks!
