Hi,

while trying to replace scrollkeeper we got some sefgaults with rarian ( 0.6.0 ) on Frugalware Linux. 

We notice first segfault while building some package , quite easy to reproduce for me.

Here a bt :


(gdb) run hu_HU scrollkeeper_cl.xml
Starting program: /usr/bin/rarian-sk-get-cl hu_HU scrollkeeper_cl.xml

Program received signal SIGSEGV, Segmentation fault.

Is trying to strlen(NULL) ...

But even rarian-example does segfaults

...

(gdb) run
Starting program: /usr/bin/rarian-example 

Program received signal SIGSEGV, Segmentation fault.
0xb7e06143 in strlen () from /lib/libc.so.6
(gdb) bt

#6  0x080488fa in main () at rarian-example.c:96

rarian is compiled with gcc 4.2.1 , glibc is 2.6.1

If you need more infos let me know.
