log for case (5)

I have seen several different conditions occur when attempting to click this
option:

1. The tab displays and seems to work correctly. I am able to select a camera
and the feed properly displays in the video window.

2. The tab displays, but then the program freezes.

3. The program displays a message box saying "Invalid floating point operation"
directly above a different message box, both for a fraction of a second before
crashing. The log says:

err:seh:setup_exception_record stack overflow 1952 bytes in thread 0053 eip
7bc45db6 esp 07c90b90 stack 0x7c90000-0x7c91000-0x7d90000
trace:msgbox:MSGBOX_OnInit L"Access violation at address 0033D6DC. Read of
address FFFFFFFF."
trace:msgbox:MSGBOX_OnInit L"Invalid floating point operation."
wine: Unhandled page fault on read access to 0xf774002b at address 0xf774002b
(thread 0034), starting debugger...
err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr
0xf74a0063

but Wine terminates before the debugger is started.

4. Similar to (3), but instead of "Invalid floating point operation." we get
"Access violation at address 7BC80D85 in module 'ntdll.dll'. Write of address
00000000."

err:seh:setup_exception_record stack overflow 1952 bytes in thread 0053 eip
7bc45db6 esp 0c0a0b90 stack 0xc0a0000-0xc0a1000-0xc1a0000
trace:msgbox:MSGBOX_OnInit L"Access violation at address 0033D6DC. Read of
address FFFFFFFF."
trace:msgbox:MSGBOX_OnInit L"Access violation at address 7BC80D85 in module
'ntdll.dll'. Write of address 00000000."
wine: Unhandled page fault on read access to 0xf777002b at address 0xf777002b
(thread 0031), starting debugger...
err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr
0xf74c007e

There are some other similar cases to (3) and (4); the second message box seems
to vary and sometimes is not present.

5. Three message boxes are launched in succession, and then winedbg is
successfully launched. winedbg then crashes internally when the backtrace is
loaded. I have given the console output for this case as an attachment.

6. Almost like (2), but the program freezes even before the tab is displayed,
and the console reports a stack overflow:

err:seh:setup_exception_record stack overflow 1712 bytes in thread 0009 eip
7bc45db6 esp 00240c80 stack 0x240000-0x241000-0x340000


I think these are most of the conditions I have observed. They seem to occur
randomly and without about equal distribution in frequency.
