Please describe the problem:
It seems there is sometimes an infinite loop in the tagmanager, causing anjuta
to freeze.


Steps to reproduce:
1.Open anjuta 
2.Open the project in the attached files 
3.if it doesn't freeze, just disable then re-enable the symbol browser plugin
until it freeze. 




Actual results:
anjuta freeze

Expected results:
no freeze

Does this happen every time?
almost every time

Other information:
It happens in the  in tm_symbol.c file, where sometimes the func
check_children_symbols calls always itself. 
I use ddd to try to find what happens but all I discovered is that this func
calls itself every times on the last line: 

check_children_symbols(sym1,sym1->tag->atts.entry.var_type)

and also on this line, sym1 always has a different
value, but sym1->tag (and BTW
sym1->tag->atts.entry.var_type) is always the same.
Perhaps is this normal, I don't know.
