[sr-dev] git:master: tmx: be sure From header is parsed before accessing the tag

[Daniel-Constantin Mierla]

I could spot the reason of looping in this case, because there is a FOR 
with CONTINUE...

Can you get the output for:

p _tmx_proc_ptran
p it
p *_tmx_proc_ptran
p *it
p slotid
p _tmx_ptran_table[slotid].plist

Thanks,
Daniel
