Do not know if it is a configuration issue or something else.
Tried removing any configuration file related to X in user home with no luck at all:

The bug is documented in bugzilla:

https://bugzilla.redhat.com/show_bug.cgi?id=1430103

I copy from there:

| I found that a very long CLASSPATH environment variable seemed to trigger the segfault. My guess is that a recent change in libpcre has made libpcre crash, if some environment value is too large.
| ...
| I removed a bunch of java packages on my system, and that seemed to bring down my automatically generated CLASSPATH to a length which no longer puts pcre in a bad mood.
| Still, if I'm right about the above assumptions, then I believe there's a bug in PCRE -- probably introduced in v. 8.40.

hi, i am having this too. just recently

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jastria Rahmat (ijash)]

in my case, it was caused by very long line of .profile in home directory. i solved it by renew it or deleting the .profile

Just confirming that this is still an issue in Ubuntu 20.10 groovy.
