Program received signal SIGSEGV, Segmentation fault.
0xb7fa259b in str_prescan (fmt=0xb7fc859b "u", va=0xbfffec1c "a\t") at
cvs_string.cpp:203
in cvs_string.cpp
The backtrace leads to line 140
zc.BrowseForService(SERVICE,CZeroconf::zcAddress)
in src/info.c
So it looks like something in cvsapi/Zeroconf.cpp is going weird...
Tracing shows

So after it gets the first response something goes wrong.
