Assertion failure in the iOS app when opening a PDF document

[tml1024]

The assertion failure is in appendBlob() in wsd/TileCache.hpp.

Backtrace below. Will try to get the JavaScript console output, too.

No, for some reason the JavaScript console is blank when I attach to the Online Editor from Safari on a Mac. Changing the assert() to code that does a sleep(200) instead of causing an assertion failure does not help.

I think that this was fixed by commit 6a77255e0348b7aa3b8b6bbff0326fdaac912b73 by removing the assert so I'll close this bug. Please reopen if you think there is still work to do.
