libgtk3-nocsd cannot be preloaded

[Cyrille37]

Hello

~$ indicator-sensors --help
ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored.
Usage:
  indicator-sensors [OPTION…] - hardware sensors monitor

indicator-sensors does not display it's version but I found that in snap folder :

$ ls -l /snap/indicator-sensors/
total 0
drwxr-xr-x 9 root root 167 nov.  27  2019 261
drwxr-xr-x 9 root root 110 juil. 27 04:17 291
lrwxrwxrwx 1 root root   3 juil. 28 11:57 current -> 291

My environment:

$ snap version
snap    2.47.1
snapd   2.47.1
series  16
ubuntu  18.04.5
kernel  5.4.0-52-generic

I found another message about libgtk3-nocsd in /var/log/syslog when launching indicator-sensors --help

Does this error cause indicator-sensors to fail? From what I can tell it should still run correctly and so should be harmless. Also what Ubuntu version are you running and does this have the gtk3-nocsd package installed?

[Cyrille37]

Hi indicator-sensors is running and gtk3-nocsd installed. It seems to me that apparmor denied some operation to gtk3-nocsd, or some thing like ...

I have just made a change to the snap which should be published to the edge channel within the next hour or two that should hopefully resolve this. So if you refresh indicator-sensors from edge in an hour say, can you let me know if it resolves the issue?
