I'm wondering if this has something to do with the "save as" system dialog. What library set contains that underlying default dialog? Here's why I ask:

I've used FMMS for years now, and routinely save contained items with "save as" to rename them on the fly. I updated (v46 to v48) on Friday, and yesterday when trying to "Save as" in FMMS (as user), the device rebooted, three times in a row. Clicking "Save", and then just renaming it with file manager afterward worked fine. But "Save as" makes it reboot.

Maybe this isn't a root related thing at all, but more a library related thing? Maybe it's making a call in to a system/kernel level routine with a parameter that was marginally acceptable with v47 and prior, but is now causing a panic condition in v48?

I can confirm, the *only* update I made in the past couple weeks was from v46 to v48. I specifically avoided updating anything else since I wanted to give v48 a run through my normal routines, as I was worried it may not be quite stable yet (which is why I never updated to v47). Oh, and I don't have R&D mode enabled, nor do I have any updates for Busybox (nor do I have CSSU installed.)

Edit: Is leafpad python based, like FMMS? If so, maybe it's the way the python "Save As" default dialog is calling in that's causing the problem. Just a thought.
