I can confirm this on 5.2-current of about a month ago, mozilla 1.6 and 
jdk1.4.2p6_1, using libkse. My trace is the same, except for libkse 
instead of libc_r. Konqueror on the other hand works fine, so it must be 
something with the plugin code and/or its interaction with open-motif. I 
have also compiled open-motif with the dnd fix.
