Error message in Solaris platform

I compiled and installed PGAdmin in Solaris platform (both S10-sparc and
S10-x86)

It works well, but I am getting the following error message whenever I
perform any operation.


** (pgadmin3:17704): CRITICAL **: file blueprint-draw.c: line 81:
assertion `GTK_WIDGET (widget)' failed


Can somebody tell the reason?


Thanks
