Blank screen when opening account

[shuyg]

I've a strange situation. When I open some accounts I receive a blank screen. After some testing we concluded that the blank page appears where there are more then four contacts associated to an account. The other accounts seams to be fine.

I tried serveral browser, users (including admin), computers, with emptying the cache, checked mysql db, etc. When I search for the account I can see them and I see the contacts associated with the account. When I look into the database there is an account (deleted=0) in accounts, a relation between account and contact in accounts_contacts (deleted=0) and a contact in contacts (deleted=0).

When I logged with level=debug, nothing out of the ordinary appeared.

Version 5.5.0 (Build 6653)

I also noticed that in some circumstances contacts are lost. The contacts are still in the contacts table, but the link between the two tables (accounts_contacts) will be lost. The acccount_id in this table is changed to another non-existing id for all contacts of the account.

No custom code.
When I open the module loader, I only see the iCal Patch. No other modules are loaded.

when this happened to me in the update wizard i renamed the cache folder to cacheold and then it worked. you could try this for accounts but i dont know how it will effect you system so i would try it on a cloned instance first. if this works copy the upload folder from the old cache to the new one. again do this on a cloned instance first, and make sure to back up
