helper app broken

[Peter Surda]

The helper app from the webext-browserpass package, located at /usr/lib/browserpass/browserpass, does not work with the current version of the browser extension. Unfortuantely I haven't been able to build it from source to debug. I originally thought it has to do with an apparmor profile, but disabling apparmor has no effect. I was able to strace it, and replicate the behaviour in a terminal (I copy&pasted the json data to stdin of browserpass).

The error I'm getting is "[Browserpass] 2019/01/06 11:31:32 Invalid action", which I see in syslog.

Upgrading the package webext-browserpass to the one from disco solves the problem, as does replacing the binary to the one from debian sid.

It looks to me like the protocol changed between 2.0.11 and 2.0.22. Looking at the github source, the "match_domain" command which the current browser extensions are using, isn't yet available in 2.0.11.
