What steps will reproduce the problem?
1. In Windows Explorer, right-click a file => PeaZip => Add to archive
2. Settings: 7z, Ultra, PPMd
3. Click "Enter password / keyfile"
4. Copy and paste 30-character password and confirm
5. Click on the "..." button for Keyfile
6. Choose File dialog pops up
** Typing the keyfile path in the textbox is ok

What is the expected output? What do you see instead?
Should allow to choose the keyfile, but it crashes PeaZip in a second or two.

What version of the product are you using? On what operating system?
PeaZip Plain 4.9.1 WIN64 installed on Windows 7 Home Premium (64-bit)

Please provide any additional information below.

Hi, thank you for reporting.
Unfortunately I'm having troubles in replicating the incident following the same procedure on the same operating system, can you kindly provide more information about how to replicate what is happening on your machine (i.e. testing situation it happens and situations it does not happen)?
Thank you in advance for your feedback.

I just tried it on another computer but was unable to reproduce this.

However, on my computer, I tried un-installing and then re-installing "peazip-plain-4.9.1.WIN64.exe" and also tried using the portable "peazip_portable-4.9.1.WIN64.zip".  In both cases, when I click on the "..." button for Keyfile, the diaglog popped up and then crashed PeaZip.  I have come up with a simple test case on my computer:

1. In Windows Explorer, right-click a file => PeaZip => Add to archive
2. Settings: 7z's default Normal, LZMA
3. Click "Enter password / keyfile"
4. Click on the "..." button for Keyfile
5. Choose File dialog pops up and then crashes PeaZip.

Below is the problem signature Windows reported.

Is there anything I can provide to help identify the issue?

Thank you very much for tracking the issue further, I'm still not able to find machines showing the same behavior.
The problem signature confirms the crash happens due to ntdll.dll, a system file that can be modified by some third party applications (see i.e. http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/programs-close-faulting-module-ntdlldll/54aaaec5-2b53-4e9f-b9a7-b7889a1cd4b6 ), as when PeaZip invokes the dialog it is a standard system component to be used at runtime.
It could be interesting trying to understand if it is a specific directory crashing ntdll.dll when browsed from file selection dialog and if other programs shows the same problem on that machine, so I could try to work around this condition i.e. starting the dialog in a different directory by default or avoiding some dialog options involved in the crash, but it is very difficult to test unless I can replicate the incident on one of my test machines.

The issue has not been replicated on test machine neither in 4.9.2 release so far.
Please re-open the bug report if it still is reproducible.
