Original GitHub issue: https://github.com/netblue30/firejail/issues/1663

When I run qupzilla (built from latest git) with firejail, it crashes with the following output. It sometimes happens within the first few seconds, and sometimes happens a few minutes later.

Output when I run firejail qupzilla in the terminal:

I have only modified the provided profile to whitelist some more folders in ~. The output of firejail --version is

firejail version 0.9.51

Compile time support:
        - AppArmor support is disabled
        - AppImage support is enabled
        - bind support is enabled
        - chroot support is enabled
        - file and directory whitelisting support is enabled
        - file transfer support is enabled
        - git install support is disabled
        - networking support is enabled
        - overlayfs support is enabled
        - private-home support is enabled
        - seccomp-bpf support is enabled
        - user namespace support is enabled
        - X11 sandboxing support is enabled

I have read issue 1112. However, that seems to be marked closed without any proper resolution. I can run Qupzilla without any problems if I don't use firejail, so I doubt it is a bug in Qupzilla.
