Netsurf-3.0: segmentation fault when opening a new tab

I am on mips64el-unknown-linux-gnu with gtk version of
netsurf-3.0. Whenever I press Ctrl+T, netsurf crashes. I used GDB
which prints the following lines when the crash occurs:

Program received signal SIGSEGV, Segmentation fault.
nsurf_ref (url=0x2be718d0) at utils/nsurl.c:1300.
1300}

I tried some GDB commands:

l gave me:

1295 assert(url != NULL);
1296
1297 url->count++;
1298
1299 return url;
1300 }

p url->count++ gave me:

284

I don't know if this information is sufficient so if you need more
info, please tell me.
