Crash when filtering log piped through stdin

[izderadicka]

lnav version
v0.12.2

Describe the bug
I have program with extensive (trace) logs - going to stdout
I piped lnav - | lnav -t
log viewing worked ok, but when I tried to apply simple out filter (just word dht) lnav crashed after hitting Enter on filter text.

Crash logs for two crashes are attached.

When I redirected stdout from program to file and started lnav on that file it works OK - I can add same filter without crash.

To Reproduce
Steps to reproduce the behavior:

1. program is rust program (rqbit) started with trace debuging
2. pipe it to | lnav -t
3. add out filter with text dht and hit Enter

Stdin pipe is not the only cause of problems,
lnav crashes also on same logs supplied from file.
When file get bigger - like 300M I got crashes when changing filter - this time crashes are bit random,

Getting crashes here even without filters:

Same thing here, doing echo hello | lnav crashes in the same way as displayed on the comment above. Reverting to 0.11.2 from 0.12.2 fixed the issue, though I have not tried any other versions in-between.

Is this reproducible outside nixpkgs?
