xxkb crashes when started under gnome with roxterm

[Max Krasilnikov]

Binary package hint: xxkb

When starting xxkb and gnome and roxterm xxxkb crashes with the following error:
pseudo@mercury at 10:12:52 ~> xxkb
X Error of failed request: BadMatch (invalid parameter attributes)
  Major opcode of failed request: 72 (X_PutImage)
  Serial number of failed request: 286
  Current serial number in output stream: 287

It is working under fluxbox great, it is working without roxterm started, but when all them started together (roxterm, gnome, xxkb)...

It was working correctly in Ubuntu 8.10.
There is "ubuntu-bug xxkb" output in attachement.
