• Gender HCI Issues in End-User Programming (where HCI stands for Human-Computer Interface)
• Gender Differences in End-User Debugging Strategies
• Gender: An Important Factor in End-User Programming Environments?
• Effectiveness of End-User Debugging Software Features: Are There Gender Issues?
• On to the Real World: Gender and Self-Efficacy in Excel
• Supporting End-User Debugging: What Do Users Want to Know?

And: "Our results indicate that males and females debug in quite different ways, that there are considerable opportunities for improving support for end-user debugging strategies for both genders, and that the types of features commonly found to aid debugging may be especially deficient in supporting strategies the females prefer to use in debugging."

The researchers were mostly females, so presumably there was little or no anti-female bias.

Intriguing, eh? So go read those papers!
