Comment 31 for bug 1720250

@Gunnar You are assuming that the bug was fixed completely by the code in /etc/profile.d/input-method-config.sh. Well, in complex entities, such as the operating systems (even in user-space level) there is no such thing as "complete, universal bugfix". There will always be some subtle cases, which the developer did not think of and these may or may not come up later, which may be 7 years later as in this case. I assume that my 20+ years of Linux kernel development experience allow me to make such a statement.

The real problem is that I have 7 other machines (identical clones) running exactly the same Ubuntu 18 system and on none of them this problem manifests itself. There are a few differences between this machine and the rest, namely:

1. I configured LVM2 on it.
2. I use bind-mounts in /etc/fstab heavily (for /usr/local and other parts).
3. I use QEMU on this machine extensively, so VFIO/PCI passthrough etc etc are configured.
4. Maybe a few other bits and pieces.

Oh well, don't worry, I won't bother you further with this. I will try to figure out the cause and will let you know if I find it.
