neomutt freeze (IMAP config)

[szaszg]

Expected Behaviour

Neomutt should never hang or freeze.

Actual Behaviour

With an IMAP config (Groupwise 2018 server), neomutt time to time freeze. Freeze on the pager screen or when viewing an e-mail, or even when sending a mail (this last is the most annoying thing).

Looks neomutt wait for data from IMAP server but never get.

When I hit Ctrl-C and say no to "Exit NeoMutt without saving? ([yes]/no):", most of the time neomutt "resurrect", but some times not (SIGSEGV).

GDB backtrace in "freeze":

Progrogram received signal SIGINT, Interrupt.
