Thanks, Michael for looking further at it. As I just said in the "Bug Hunt
Sunday" thread, I'm down to only about 50% reproducible now. I only 
just noticed this thread otherwise I'd have only replied here.

Were there any Unicode characters anywhere in the path? Files with 
Latin character names in folders with Unicode names are also a reported
problem.  

Is there any relevance to the act of changing the name, then 
reimporting the contents? That was replicating so reliably that it 
looked more than coincidence. I have just got a crash by changing 
a file called "bbb" to "bbbz" in a completely Latin path and then 
right-click > Open with (after successfully importing a file with a 
Unicode name). However the crash report looks identical to the 
report after importing a file with a Unicode name.

OK I'll try that on my machine if not advised otherwise.

If I'm reading this correctly:
http://docs.wxwidgets.org/trunk/overview_changes_since28.html#overview_changes_unicode 

we may have to change a lot of c_str() instances when we upgrade to 
Widgets 3.x.
