Comment # 2 on bug 1082956 from Kristyna Streitova

This is probably related to apparmor (similar as bug 917431). According to
strace, lessopen receives "Permission denied" when it wants to run
/usr/bin/rpm:

execve("/usr/bin/rpm", ["rpm", "-qip", "\"./mariadb-tools-10.2.9-34.2.x86"...],
0x55f47e135380 /* 58 vars */) = -1 EACCES (Permission denied)

I'm assigning it to Goldwyn Rodrigues. Can you please take a look? Thanks!
