Nautilus (and other apps) force-close unless run as root

[Wolter HV]

After I upgraded from Ubuntu 14.10 to Ubuntu 15.04, I have been noting stability problems of many applications. They force-close randomly or when I trigger certain actions. Some of this apps include nautilus, gnome-maps, nemo, gnome-control-center, evolution, and others that I may not know of.
I have checked dmesg and syslog and I can see that all of the crashes report a segmentation fault, something about 0 ip and error 14. Below you can see some example dmesg lines:

gnome-control-c[3930]: segfault at 0 ip (null) sp 00007fffcbccb708 error 14 in gnome-control-center.real[400000+3aa000]

nemo[5773]: segfault at 0 ip (null) sp 00007fff9ae1d118 error 14 in nemo[400000+183000]

gnome-maps[5811]: segfault at 0 ip (null) sp 00007fff32111558 error 14 in gnome-maps[400000+3f000]

In this 3 examples, all I did was:
In ...
gnome-control-center: I unlocked with my password the users section
nemo: I just navigated to some folders and let the application alone, then it crashed after a minute
gnome-maps: I tried to get directions

This was not happening before the system upgrade.

I tried to use apport-retrace but I didn't know which argument to pass. If I passed the crash file at /var/crash then it attempted to download some files and then nothing else happened.
