Bug report: drawBitmap / drawBitmap2 crashes the device when rendering an image from Application.Storage after device reboot

My app downloads a PNG image of a map (around 10KB in size) and that image gets stored to application storage via Application.Storage.setValue("lastImage", imageData) so that if the user exits the app and re-opens it, the image is can be pulled from storage and displayed immediately without having to wait for download again. The image is drawn to the screen with Graphics.drawBitmap2() typically.

This is all working fine for the most part: images are downloaded, stored, displayed, etc. The problem is after device reboot / sleep. Then when I load the app, it and the device crash instantly. This happens on an Edge 840 solar. Everything works fine in the simulator, but you can't simulate a reboot / restart of the app there. If I comment out the drawBitmap2() call, the app loads no problem (with no image displayed), but it will begin crashing again once that line of code is back. To fix it I first have to create a version of the app that writes null to the "lastImage" key and cleans up whatever bad data seems to have gotten in to the storage.

I'm using SDK 7.3.1 and API level 4.1.0, but it also seemed to happen with API level 5.0.0.

As just a small quirk I've seen: occasionally the image loads without crashing the app, but it's real strange: it looks super zoomed in and interlaced almost. I'm able to refresh it within the app (since it didn't crash) and it starts looking normal again, but it's definitely not being saved that way to storage deliberately.

The log left in Debug/Uploads/Error/err_log.txt after a crash is this:

Any help here is appreciated! I know it's a bunch of function addresses that only Garmin folks are going to know about, but I've been really racking my brain here: trying smaller images, quantizing the colors on device, quantizing on server, converting the downloaded image to a BufferedBitmap or Bitmap before rendering it, moving code from onStart() to onLayout(). Nothing seems to make a difference.
