[Bug 1458340] Re: nm-applet crashs with segmentation fault (Cannot grab information for modem at /org/freedesktop/ModemManager1/Modem/7: No ModemManager support)

 

I've got the same problem after updating from vivid to wily.

Usually one of the wi-fi or mobile internet connections are affected. The problem arises occasionally, somtimes immediately after bootup, sometimes ater resume from sleepmode. If it's the case in the syslog appears a similar warning how described in the initial post.
Additionally this warning occures:
gnome-session[1487]: (nm-applet:1690): nm-applet-WARNING **: ModemManager is not available for modem at /org/freedesktop/ModemManager1/Modem/0

Title:
  nm-applet crashs with segmentation fault (Cannot grab information for
  modem at /org/freedesktop/ModemManager1/Modem/7: No ModemManager
  support)

Status in network-manager-applet package in Ubuntu:
  Confirmed

Bug description:
  This bug is regarding the nm-applet only. I am able to use WiFi and 4g
  modem connections without any problem but I do not have a GUI to
  manage the connections or choose one as the applet does crash whenever
  I try to run it:

  This is howit looks like:
  (nm-applet:9942): nm-applet-WARNING **: Cannot grab information for modem at /org/freedesktop/ModemManager1/Modem/7: No ModemManager support
  Speicherzugriffsfehler (Speicherabzug geschrieben)

  Where do I find the core dump in order to provide it as well?

  Any idea howto fix this issue?

  My setup:

  I am using a Lenovo x240 laptop and a ThinkPad EM7345 4gLTE modem (see
  http://support.lenovo.com/us/en/documents/pd031021 for details) .

  There is no package called 'network-manager-applet' so I provide the
  data for 'network-manager': 0.9.10.0-4ubuntu15.1

  Ubuntu Version: 15.04
