Mozilla-thunderbird, vmware and acroread7 on LE2005
 

I just upgraded to Mandrivalinux Limited Edition 2005 on my desktop, and there are some problems I met. I installed vmware workstation 5.0 and mozilla-thunderbird but neither of them works.
For mozilla-thunderbird the program cannot be started, and the error message was
*** glibc detected *** free(): invalid pointer: 0x08ee8ec0 ***
thunderbird/run-mozilla.sh: line 159: 2517 Aborted "$prog" ${1+"$@"}".

For vmware workstation the program can be started but it froze there and have no response at all, the error message was
*** glibc detected *** free(): invalid pointer: 0x08eb0660 ***
NOT_REACHED /build/mts/release/bora-13124/bora/apps/vmuiLinux/sig_vmui.c:390

Finally I even cannot use the acroread7 built in LE2005. Every time I type "acroread7" on command line the program start and shut down immediately.

I think all these problem are kind of related, but I don't know how to do with it. So does anyone have some ideas of these problems? Any suggestions will be helpful and appreciated.
