Status changed to 'Confirmed' because the bug affects multiple users.

Also crashing when plug in my iphone, on my desktop computer

[bar (barhofesh)]

after deleting KDE desktop packages

[shawnlandden (shawnlandden)]

This NULL deference when HOME is not defined appears to be fixed in the latest version of libmobiledevice (or rather libmobiledevice git) in src/usrprefs.c:userprefs_get_config_dir()

reassigneing to where bug is coming from

[shawnlandden (shawnlandden)]

actually, I still don't like the user of getenv("HOME"); over

               struct passwd pwd;
               errno = 0;
               pwd = getpwuid(getuid());
               if (pwd)
                       cdir = pwd->pw_dir;
               else {
                       //error handling
               }

Raising to High.. 412 affected == a big problem

[Stefan Stutz (sstutz)]

crashed after plugging in my iPhone

[Adam Dingle (adam-yorba)]

Just like the previous commenter, I saw this crash right after I plugged in my iPhone.

[Wolf Rogner (war-rsb)]

I have upowerd 0.9.17-1build1 installed.

It crashes on every resume from RAM (even when the monitor just dimms).

afaic this is not fixed at all

(12.10 64bit Mac running the latest patches)

hi,
for me, this bug happened after lubuntu-upgrade to 12.10
then, i made a fresh install, from mini.iso, only with the necessary
packages for me, and the problems disappear.
