write-region is mishandling an error

[Richard Bielawski]

I couldn't get my data into a file using with-temp-file.
All I got was an empty file.
I eventually traced this command 
(with-temp-file "Test at 12:05.txt" (insert "Hello"))
down to 
* write-region(1 5 "Test at 12:05.txt" nil 0)

Which creates an empty file named "Test at 12" and no error occurs.
Initially I didn't notice that the filename was truncated.
Once I did I realized that : is illegal in a file name.
Some kind of error must be occurring that isn't being reported.
Turning debug-on-error on didn't show an error either.
