LogDialog sometimes hangs

Hey.

I noticed that a rather old revision (yes I see no changes that could have changed that behavior since that revision) has Log Dialog hanging sometimes. I have no idea what it depends on - just once in a while I when ask to show the changelog the dialog appears and hangs gray for ages, Task Manager shows full load of the CPU core.

I attached the debugger and what I'm seeing is that it hangs inside CLogDlg::ResizeAllListCtrlCols(bool bOnlyVisible) with "bOnlyVisible" set to true. It is inside the loop:

for (size_t index = startRow; index<endRow; ++index)

with "endRow" being shown as 0xFFFFFFFF by the debugger. So looks like for whatever reason "endRow" somehow became -1. "endRow" is being initialized by the following code:

startRow = m_LogList.GetTopIndex();
endRow = startRow + m_LogList.GetCountPerPage();

Do you have any idea of why "endRow" could have become equal to -1?

Thank you.
Dmitry.
