Program received signal SIGSEGV, Segmentation fault.
0xb7fa259b in str_prescan (fmt=0xb7fc859b "u", va=0xbfffec1c "a\t") at
        in cvs_string.cpp

The backtrace leads to line 140
in src/info.c

So it looks like something in cvsapi/Zeroconf.cpp is going weird... 

Tracing shows

13:57:55:   -> wrap_add(*.xls -kb, 0, 0)
13:57:55:   -> wrap_add(*.zip -kb, 0, 0)
13:57:55:   -> wrap_add(*.Z -kb, 0, 0)
13:57:55:   -> Zeroconf ipv4 response from caxton.local:
Segmentation fault

So after it gets the first response something goes wrong.
