Two different crashes observed but use case are quite similar and call stacks
indicate root cause might be same so reporting them as one.
The use cases are like this:
Crash #1
1. Capture or open a big capture file.
2. Save capture file
3. While save file operation is ongoing..
4. Open "Capture Options" dialog
5. Start new capture
6. Crash observed.
Crash #2
1. Capture or open a big capture file.
2. Set a display filter
3. While rescanning is ongoing..
4. Open "Capture Options" dialog
5. Start new capture
6. Crash observed.
The use case is perhaps a bit odd but it has happened to me by accident a
number of times as the UI allows it.
Crash #1 - Start capture while saving capture file...
