Floating point exception on start

Recommended Posts

I recently am unable to start Enpass:

torre 0 ~ ↠ /opt/enpass/Enpass 
QFile::remove: Empty or null file name
QQmlComponent: Created graphical object was not placed in the graphics scene.
QQmlComponent: Created graphical object was not placed in the graphics scene.
QQmlComponent: Created graphical object was not placed in the graphics scene.
QQmlComponent: Created graphical object was not placed in the graphics scene.
Floating point exception (core dumped)

I've tried removing my enpass directory, `.config/sinew.in` files, and removing & reinstalling Enpass using apt-get.

Does anyone have any suggestions? I had a look at the strace, but I'm not savvy enough to see a smoking gun.

I'm facing the exact same problem, same exact error message here and I also don't know how to properly analyze the core dump. For me it also started last week.

@miles is it working again for you?

I'm running Ubuntu 18.04.2 LTS.

Oh, just after replying to this thread I managed to get my installation working again.

The problem was that due to scaling problems I followed this FAQ and set the two environment variables to the following  (note the 0.9 in the second line):

export QT_AUTO_SCREEN_SCALE_FACTOR=0
export QT_SCREEN_SCALE_FACTORS="0.9;1"

After changing it to the following it worked again perfectly:

export QT_AUTO_SCREEN_SCALE_FACTOR=0
export QT_SCREEN_SCALE_FACTORS="1;1.5"

I find it quite bizarre since it has been working fine for half a year, maybe it had to do with some QT update.

Interesting. I see that that QT_SCREEN_SCALE_FACTOR is set in my environment, but I have no idea why. Unsetting them works. Thank you!
