Comment:
It looks like stack corruption given the backtrace:
{{{
#0 0x00000000004873c2 in pgp_getkeybystr (p=<optimized out>,
abilities=2, keyring=<optimized out>) at ../pgpkey.c:997
}}}
Line 997 is the end of said function:
http://sources.debian.net/src/mutt/1.5.23-3/pgpkey.c/#L997
Corruption is only possible if {{{l==0}}} (because then {{{l[p-1]='!'}}})
The new backtrace from the reporter confirms it:
{{{
Breakpoint 1 at 0x487110: file ../pgpkey.c, line 926.
Continuing.
Breakpoint 1, pgp_getkeybystr (p=0x7fff0c5c7c70 "", abilities=2,
keyring=PGP_PUBRING) at ../pgpkey.c:926
926 ../pgpkey.c: Aucun fichier ou dossier de ce type.
