Clashes on Ubuntu when saving a file

[edips]

Hi. It was working fine on Manjaro OS. It clashes when I save a text file on Ubuntu 19.10.

qml: edit page completed
saved to "/home/edip/workspace/deneme/d2"
QUrl("file:///home/edip/workspace/deneme/d2") "/home/edip/workspace/deneme/d2"
Segmentation fault (core dumped)

Can you record a core dump? To do so run ulimit -c unlimited in terminal, then run liri-text and make it crash. A core file should appear in your home directory (if it's not there check /proc/sys/kernel/core_pattern for core file naming pattern).

After crash, there is a core file, it is 116 MB. core_pattern file is |/usr/share/apport/apport %p %s %c %d %P
I attached core file.
core.zip
