+I haven't quite decided what to do about this yet, but I thought I'd get\r
+this on the record, because it seems to me a few people have been having\r
+problems with this.\r
+\r
+FWIW, I tested with various versions of xapian and libgmime, but the\r
+problem still exists for gmime 2.4.25-1, and xapian 1.2.5-1, both\r
+recompiled for squeeze.\r
+\r
+If you install the libxapian22 from sid, then gcc and libc6 are both\r
+upgraded, and the problem goes away (but you are not really running\r
+squeeze anymore).=20=20\r
+\r
+About the only good news is that the symbol hiding test does indeed fail\r
+on squeeze i386.\r
+\r
+I have appended part of the backtrace, in case anyone finds it\r
+illuminating. As far as I can tell without line numbers, the catch in\r
+_notmuch_message_remove_term is failing. I suppose this could be the\r
+kind of "exceptions start mysteriously malfunctioning" that\r
+http://gcc.gnu.org/wiki/Visibility warns about.\r
+\r
+Xapian _seems_ to do the right thing with visisibility\r
+declarations for these exception classes.\r
+\r
+I don't know what, if anything to conclude from the fact that everything\r
+seems to work fine in gcc 4.6.\r
