ZecWallet v0.9.7 fails on Debian 9

I’m having trouble with the latest (0.9.7) fullnode version of ZecWallet on fully updated Debian 9. Installation (after uninstalling old version) produces the following output:

$ sudo dpkg -i Zecwallet_Fullnode_0.9.7_amd64.deb
Selecting previously unselected package zecwallet.
(Reading database … 159300 files and directories currently installed.)

Attempted execution from a shell fails:

$ zecwallet
Trace/breakpoint trap

Any ideas on how to fix this would be very much appreciated.

There’s already an issue filed for this here: Trace/breakpoint trap on Debian 9 · Issue #245 · ZcashFoundation/zecwallet · GitHub

tldr; solution is to run with zecwallet --no-sandbox

That seems to work:

$ zecwallet --no-sandbox
Fontconfig warning: “/etc/fonts/fonts.conf”, line 100: unknown element “blank”
ATTENTION: default value of option force_s3tc_enable overridden by environment.

The wallet GUI window appears, syncs, and everything seems as expected.
Thank you very much!
