[Evolution-hackers] hang of evo when access ldap AB

["leon.zhang" <leon zhang sun com>]

hi, toshok

I often meet hang of evolution 1.4.5 when query info from ldap server.

Normally if I click a simple string(one time), like as "leon", i can access some cards from ldap server,
but if I click "leons" sevral times quickly, i will find the evo freezed now!!!
(btw, searching "leons" should not receive any AB info too)


when evo freezed, I print the two stacks in evolution and wombat process(details is in the last part of this email).

I get the simplfied calling relationsship below:

                ---------------------------------------------------------------------



From the calling map above, I guess the evo hang because wombat has been hanged.

Further more, pas_book_view_dispose() 's calling "bonobo_object_release_unref (book_view->priv->listener, NULL);"
might be the direct source of this hang.

If I comment out that line, there exist no hang at all.

I feel suprised why commenting out the line can fix this hang, and what is the exact source of this hang.

can you give some suggesions or comments?

thx
