File not found error after downloading causes winetricks to download a file twice

[GoogleCodeExporter]

What steps will reproduce the problem?
1. winetricks anything that isn't in the winetricks cache, in my case qqintl

What is the expected output? What do you see instead?
After completing the download the first time, I got:
/usr/local/bin/winetricks: line 456: QQIntl2.11.exe: No such file or directory
------------------------------------------------------
Checksum for /Users/apple/.cache/winetricks/qqintl/QQIntl2.11.exe did not 
match, retrying download
------------------------------------------------------

What version of the product are you using? On what operating system?
Git HEAD, 20150114 - sha1sum: 5850eb6daa8d25182051b027a1c194cd5245def7, OS X 
10.9.5 (Darwin)

Please provide any additional information below.

Running `openssl sha1 /Users/apple/.cache/winetricks/qqintl/QQIntl2.11.exe*` 
gives me two identical SHA1 sums, with one of filenames prefixed with .bak. The 
file size matches, too.
