When running either 4.6 or 4.7 versions of Editor in OSX 10.9, I am unable to open files.
This issue is not present in previous versions of engine. Any command that results in opening a Finder window to select a file will crash my editor.
In 4.6, crash occurs as soon as window opens.
In 4.7, problem is more complex. Under certain circumstances, it will crash, but under rest it simply hangs indefinitely. I have not been able to pinpoint which steps cause what behavior.
These are quickest steps to reproduce problem:
- Launch Unreal Editor from Epic Launcher
- When Project Browser window appears, click ‘Browse…’
- In resulting Finder window, do one of following:
- Expand a directory
- Collapse a directory
- Select a location from sidebar
In Unreal Editor 4.6, crash occurs on step 2.
In Unreal Editor 4.7, crash occurs in step 3.
system tends to crash when expanding a directory, but is more likely to hang when collapsing one.
It is possible to open a project file if it appears in open directory.
It is also sometimes possible to select folders from sidebar. For example, I tried to access my downloads folder.
first attempt resulted in a crash. Every subsequent attempt has worked, but it still fails to expand or collapse directories inside downloads folder.
Each time editor is reloaded, it retains state following action that caused crash. This means that, given window above, when I collapse ‘Source’ directory, editor crashes. When I reopen it, it shows me following folder structure:
This tells me that at some level editor manages to access folder, but something goes wrong when it tries to read contents. crashes don’t seem to have same root cause every time, but they generally are either a null pointer exception or a memory access violation.
