apport retrace failed because as shown in ProcMaps.txt the file system hierarchy is not the standard (e.g. /rofs/usr/lib/firefox/firefox-bin).

Assigned to me for retrace.

[Hilario J. Montoliu (hjmf) (hmontoliu)]

Retrace done (unable to get a better one).

Extract from retraced stacktrace:

Tagging as mt-confirm mt-needtestcase for further processing
