squat core dump

Hi, I'm getting a core dump while squattering folders, always on the same folder:
08045e68 libcyrus.so.0.0.0`charset_extractitem+0x218(8052d40, 804604c, a6, fe9607c9, 439b, 0)
08045ea8 libcyrus.so.0.0.0`charset_extractfile+0x33(8052d40, 804604c, a6, fe9607c9, 439b, 0)
08046008 libcyrus_imap.so.0.0.0`index_getsearchtext_single+0x60a(80779e8, a6, 8052d40, 804604c, 6c756166, 74)
08046158 squat_single+0x26b(0, 806a320, 1, 0, 0, 0)

08047a08 main+0x39a(80479fc, fef726a8, 8047a34, 8052973, 5, 8047a40)

any chance to discover the msg uid or id that's causing it?
Thanks
