I like it! A few random points:
* Shouldn't pidgin_crash_minidump_print() be declared in a .h file?
* I'm fine with C++
* Is there a reason for using the file extensions .cc and .cpp for c++
files? Could we standardize on one or the other? My vote would be
* I agree with John and Richard that it would be nice if we could use
a library standalone library instead of including all the crash
reporting code itself (whether it be Breakpad or apport or something
else), even if that library isn't included in many Linux
* Does the current diff just print to stdout? Does the
"crashreporter" program exist? Is that a part of Breakpad?
* What happens to the crash report? Will the user be prompted to send
it to us or something? Do we need something set up on our servers to
accept incoming crash reports? And if so, is it possible for the
crash reports to contain private user data? And if so how will we
make sure only trusted devs have access tot he crash reports?
This looks pretty sweet.
