Comment:

 Replying to [comment:4 gk]:
 > We could then bisect the offending commit and help Mozilla with a fix
 (which we would backport for Tor Browser until we pick it up).
 lol you're too kind :P I expected that you wouldn't care much in view of
 the ton of work that you have.

 > Does anyone know how to reproduce this problem reliably? Like, what
 environment does one need to have to hit this issue?
 I hit that after a transition from Ubuntu 17.10 -> Ubuntu 18.04 -> Lubuntu
 18.04 where I messed up and ended up breaking and deleting many packages,
 I didn't even have `zlibc` installed (after installing it the problem
 didn't happen - so far), so I guess remove `zlibc` and something else if
 needed and do the procedure I described in comment:1.
