gimp2 does not open image files on (on ppc?)

[barracuda156]

I get the following error when trying to open random files like screenshots:

Plug-in crashed: "file-png"
(/opt/local/lib/gimp/2.0/plug-ins/file-png/file-png)

The dying plug-in may have messed up GIMP's internal state. You may want to save your images and restart GIMP to be on the safe side.

Same error for jpeg and png. What may cause this?

16. S. Just not to forget, we need legacysupport.redirect_bins gimp for gimp* ports, otherwise there is a disaster on launch with malloc errors.

You'll have to search the gimp issue tracker or elsewhere on the Internet and see what people say. I found this issue in which the last comments identify it as an out-of-memory problem that occurs on 32-bit systems, but I don't know if it's exactly the same issue as yours:

​https://gitlab.gnome.org/GNOME/gimp/-/issues/4428

If there was truly a crash, as the error message suggests, then check if macOS wrote a crash log file; if it did, attach it; maybe it helps pinpoint why the crash occurred.

@kencu also provided the following suggestion, to help with generating a detailed crash report:

If I were a gimp developer, and with this amount of information, the next thing I might ask you to do would be to launch gimp using lldb like this:

lldb gimp

then after the initial flurry of activity have you type:

run

and then, presuming it crashes again with "fatal error: Segmentation fault: 11", I would have you type:

bt

to get the stack trace, and then copy that information and paste it into the bug report.

Sorry, I missed the reply here.

I will try to debug what’s going it, we want GIMP working.

Does this say anything? (There are a lot of malloc errors on start-up, but they do not lead to the crash. But opening an image in a non-native format crashes it.)
