'Cannot perform malloc' error

[Joachim Trinkwitz <upp105@ibm.rhrz.uni-bonn.de>]

Hi,

after installing the new slink netscape binaries (4.5-1) I get this
error messages when starting the program:

ERROR: /usr/lib/netscape/45/communicator/plugins/libnullplugin.so: undefined symbol: FE_GetToplevelWidget
Cant load plugin /usr/lib/netscape/45/communicator/plugins/libnullplugin.so. Ignored.
Warning: 
    Name: openOrBringUpBrowser
    Class: XfeButton
    Creating an active drop site with no drop proc.

Error: Cannot perform malloc

What does this mean, and what can I do to get netscape up and running?

Clueless,
joachim
