To summarize the numbers a bit:
Male uploads that were overwritten by anyone: 7226
Female uploads that were overwritten by anyone: 536
None uploads that were overwritten by anyone: 21484
Male uploads that were overwrote anyone: 6775
Female uploads that were overwrote anyone: 619
None uploads that were overwrote anyone: 21861
As a percentage of all overwritten uploads
Male: 24.7%
Female: 1.8%
None: 73.5%
As a percentage of all uploads that overwrote someone
Male: 23.2%
Female: 2.1%
None: 74.7%
Assuming random assortment, we would expect:
Male-male: 0.247*0.232 = 5.7%
Male-female: 0.52%
Male-none: 18.5%
Female-male: 0.42%
Female-female: 0.038%
Female-none: 1.3%
None-male: 17.1%
None-female: 1.5%
None-none: 54.9%
Given the number of events observed, that translates to expectations of:
Male-male = 1667
Male-female = 152
Male-none = 5412
Female-male = 122
Female-female = 11
Female-none = 380
None-male = 5003
None-female = 439
None-none = 16061
These numbers are broadly consistent with what you posted. There are some
deviations, but given the sample size and the number of possible
confounding factors (some of which have been mentioned by others) I think
you'd need evidence of a quite large effect before assuming there was an
important bias.

I have pulled together the following table together
for the past 360 days,
counting whenever an image was reverted by someone who was not the last
uploader, and then attempting to find any declared gender:
2014-2015 Commons file overwrite stats compared to gender
+---------------+----------+
| sex | count(*) |

| female-female | 1 |
| female-male | 110 |
| female-none | 426 |
| male-female | 139 |

+---------------+----------+
Key: "none" means not set in user preferences, "female-male" means a
woman
has overwritten a man's file and "male-none" means a declared male has
overwritten an account with no gender set.
I'd appreciate any views on whether there is any statistical meaning to be
pulled from these figures, apart from showing that men probably outnumber
women contributors by ten times on Commons.
If the email is displaying badly, you can find a wiki formatted table and
original generating SQL on the Commons village pump[1]. I thought this
would be of wider interest as though "image revert warring" is mostly an
issue for Wikimedia Commons, it is a very similar area of heated disputes
when compared to edit revert warring on Wikipedia projects. The question
popped up from someone interested in my long running 'significant reverts'
tracking report.[2]
