Bug Description
In geis_xcb_backend.c, axis labels are retrieved from the server. If the axis isn't labeled, a static string constant is used instead. However, at the end of the axis handling, XFree is called on the axis label no matter what. This may cause XFree to be called on the static string, resulting in a segfault.
