general protection fault in libgobect-2.0 #105
Description
This was found when trying to add a second user with lxqt-admin-user in the sudo group and then trying to use it again to remove the group membership. It appears that during this process, lxqt-policykit crashes, causing the change to fail.
Expected Behavior
lxqt-policykit doesn't crash.
Current Behavior
lxqt-policykit crashes. Example message (note this is a little old, but I've tested it with even earlier version as well as git master and the result is the same, with version numbers changed, obviously):
[ 764.849494] traps: lxqt-policykit-[1598] general protection fault ip:7f8c94773671 sp:7ffc5acf6618 error:0 in libgobject-2.0.so.0.6400.2[7f8c94745000+36000]
Steps to Reproduce (for bugs)
- Use lxqt-admin-user to create a second user (let's call it user2)
- Use lxqt-admin-user to add user2 to sudo
- Logout and back in again (yes, this is a requirement to reproduce— if you want, you can first remove user2's sudo and it will work, but then add it back and continue on)
- Use lxqt-admin-user to try to remove user2's membership in the sudo group
System Information
I'm just going to clip all this because it seems to affect versions new and old, so the version information really doesn't seem to matter at all. I did verify this in the Lubuntu CI builds of Git master, so I'm confident the problem still exists.
That said, I only checked Lubuntu systems. It's possible there is some underlying issue here that may be specific to our project. Using pkexec (but not sudo) seems to fail similarly as lxqt-admin-user.
Original bug here BTW.
