This says that at callbacks.c:399, xfcalendar is trying to write a
record of length 135702688 (135 MB), which is definitely wrong. It means
that the strlen function failed. Try the following patch. Maybe the
DBH_Size function only works on an open DBHashTable.

BTW, xfcalendar does not compile on gtk-2.0.6:

/fast/CVS/sourceforge/xfce/xfce4-extras/xfcalendar/src/main.c:185:
undefined reference to `gdk_screen_get_default'
/fast/CVS/sourceforge/xfce/xfce4-extras/xfcalendar/src/main.c:185:
undefined reference to `GDK_SCREEN_XSCREEN'


regards,

Edscott
