Hi! When I try to run the attached test.py after adding the attached email (4EFC743A.3060609_april.org) to notmuch db I got a segmentation fault (gdb bt attached). This is what I think a relevant part of the gdb: ~~~~~~~~ (gdb) frame 1 #1 0x00007ffff5f2759c in g_mime_iconv_open (to=0x761ef0 "UTF-8", from=0x83d590 "iso-8859-1") at gmime-iconv.c:261 261 if ((node = (IconvCacheNode *) cache_node_lookup (iconv_cache, key, TRUE))) { (gdb) list 256 key = g_alloca (strlen (from) + strlen (to) + 2); 257 sprintf (key, "%s:%s", from, to); 258 259 ICONV_CACHE_LOCK (); 260 261 if ((node = (IconvCacheNode *) cache_node_lookup (iconv_cache, key, TRUE))) { 262 if (node->used) { 263 if ((cd = iconv_open (to, from)) == (iconv_t) -1) 264 goto exception; 265 } else { (gdb) print iconv_cache $1 = (Cache *) 0x0 (gdb) ~~~~~~~~ iconv_cache is initialized in g_mime_iconv_init() that is called by g_mime_init(). notmuch CLI show the message correct. I know nothing about gmime or notmuch code, but can this be the case of the python bindings not calling g_mime_init() correctly? Regards, Kazuo Teramoto
