[Bug 306120] Re: mtpfs causes repeatable segfault

[calder]

Same problem here, mtpfs crashes when the root directory contains a
file's or folder's name contain "@" or "&". Possibly will crash if any
special characters are used with file names.

[Alexander Fortin]

I'm getting same results as for Gavin Hamill, mounting my Creative Zen
and accessing data it gives segfaults:

from dmesg:
mtpfs[8788]: segfault at 4 ip 0804b976 sp b6c80130 error 4 in 
mtpfs[8048000+5000]

$ df -h /media/zen
df: `/media/zen': Transport endpoint is not connected

[Bug 306120] Re: mtpfs causes repeatable segfault

[Chris Coulson]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. However, your crash report is either missing or
challenging to deal with as a ".crash" file (it's missing debugging
symbols). Please follow these instructions to have apport report a new
bug about your crash that can be dealt with by the automatic retracer.

If you are running the Ubuntu Stable Release you might need to enable
apport in /etc/default/apport and restart. Once you have done this,
repeat the steps necessary to recreate the crash.

If you sdon't see a crash notification and are using Ubuntu with the Gnome 
desktop environment - launch nautilus and navigate to your /var/crash directory 
and double click on the crash report you wish to submit.
If you are using Kubuntu or Xubuntu you can file the crash using 
/usr/share/apport/apport-qt --crash-file=/var/crash/_my_crash_report.crash in a 
terminal - where _my_crash_report.crash is the crash you would like to report.

I'm closing this bug report since the process outlined above will
automatically open a new bug report which can then dealt with more
efficiently. Thanks in advance for your cooperation and understanding.

For completeness, this also segfaults when I try version 0.9 from the
author's site at http://www.adebenham.com/mtpfs/
