Special european characters

@Waldknoblauch can you explain a pages where you get this kind of errors?

I get the same/similar error/warning/exception, but I am not using special characters in the usernames.

This occurs for me when switching back from masquerading to the original logged in user.

Warning: array_flip() [function.array-flip]: Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->load() (line 178 of /<path>/includes/entity.inc).

The issues in #2 occur on a site that does not have "real name registration".

So, if i use the "real name registration" module, the problem could be solved?

@thedayway: No, that probably will not solve the issue.

thx, but what does?

@thedayway:

Adding the "real name registration" module will probably *not solve* the issue.

Fixed in #1087744: Warning: array_flip

test a current DEV before next RC

AndyPost: Thanks for solving that.

Resolved my issue from #2.

Makes testing on my laptop *much* easier.

Great work!
