[Apport retracing service (apport)]

This crash has the same stack trace characteristics as bug #758824. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

Is this bug still reproducible?

no recent comments; is it solved now ?
