I am trying the new idb GUI, and found that every time I try to start the help, it crashes, with the message
JVM terminated. Exit code=127
It looks similar to issues I had previously with the Eclipse included in IDL 7.0, which was incompatible with the XulRunner library that provides the Gecko engine in my system (Fedora 9 x86_64). That is using idb for intel64. If I try to use it with ia32, idb does not even load, with a mismatch in ELF class (even if I put in my path a 32 bit JRE).
