Comment 1 Martin Stransky 2008-06-02 10:01:25 UTC 
Hmm, that's really strange. I'll try to reproduce it.
Comment 2 Alexander Boström 2008-06-05 14:10:42 UTC 
Hmm... Without -v, I get:

31915 access("/usr/lib/nspluginwrapper/npconfig", X_OK) = 0
31915 clone(child_stack=0,
flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0xb7fd2708)
= 31919
31915 waitpid(31919,  <unfinished ...>
31919 execve("/usr/lib/nspluginwrapper/npconfig",
["/usr/lib/nspluginwrapper/npconfig"..., "-p"..., "nswrapper_32_32"..., "-d"...,
"/usr/lib/mozilla/plugins-wrapped"..., "-i"...,
"/usr/lib/mozilla/plugins/nphelix.so"...], [/* 46 vars */]) = 0
31919 brk(0)                            = 0x99e6000
...

With -v, this happens:

31895 access("/usr/lib/nspluginwrapper/npconfig", X_OK) = 0
31895 clone(child_stack=0,
flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0xb7f4e708)
= 31899
31895 waitpid(31899,  <unfinished ...>
31899 write(2, "INFO: ", 6)             = 6
31899 --- SIGSEGV (Segmentation fault) @ 0 (0) ---

So apparently it works when there's a segfault.

I'm trying to catch it in gdb but it's eluding me there.
Comment 3 Martin Stransky 2008-10-22 11:47:23 UTC 
Actually the problem is that the -v argument causes plugin-config segfault....
Comment 4 Martin Stransky 2008-10-22 11:55:38 UTC 
Fixed in Rawhide, wontfix for the current RHEL line.

Anyway, /usr/bin/mozilla-plugin-config -i -f is the right command, don't use -v on rhel-5. The wrapped plugins have "nswrapper_arch_arch" prefix, so the wrapped flash is  in nswrapper_32_32.libflashplayer.so file. (or nswrapper_32_64.libflashplayer.so for 32->64 direction)
