Re: cairo crash on NetBSD/sparc

fine! it doesn't crash anymore as before and I get the copy/paste 
contextual menu.

Now I think that the crash happens depending on the remote display I 
export to!

1) export workstation with FreeBSD 8.4, seems to run fine (I will stress 
it more, but font panel comes up, I can type, I get the contextual menu, 
etc)
2) export to laptop with FreeBSD 10.0 and Ink will die quite soon

Both machines are intel x86 (thus both little-endian and pretty 
standard), are running the system Xorg, 32bit, the output of xdpyinfo 
looks similar except for the workstation having a larger display and a 
strange resolution (90x89). But there it works! I get the crash with a 
more recent and more standard setup.

For what differences could I look in xdpyinfo? or elsewhere?
