maildirlock fails

[Martynas Bendorius]

Hello,

Maildirlock seems to panic on locking:
[root at centos7 home]# /usr/libexec/dovecot/maildirlock "/home/user/imap/domain.com/email/Maildir" 10
Panic: BUG: No IOs or timeouts set. Not waiting for infinity.
Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0xd90ee) [0x7f5bf02f10ee] -> /usr/lib/dovecot/libdovecot.so.0(+0xd9131) [0x7f5bf02f1131] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f5bf0256efd] -> /usr/lib/dovecot/libdovecot.so.0(+0xf078c) [0x7f5bf030878c] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x36) [0x7f5bf030b1f6] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x56) [0x7f5bf03099c6] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f5bf0309be8] -> /usr/libexec/dovecot/maildirlock(main+0x24a) [0x558ae0e032ca] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7f5befe6d3d5] -> /usr/libexec/dovecot/maildirlock(+0x13a2) [0x558ae0e033a2]

Is this a known issue?

Thank you!
