The only real difference betwen 5.3 025 and 5.3 026 is to fix that crash. Most people will be happy updating to 026 instead of flashing so not a major issue. For those who prefer not to update and flash and restore, they will have to install python lxml to avoid the crash. Those on 5.3 026 or 5.3 024 and lower will not be affected
opkg install python-lxml
Or download and transfer zipped image. Grog's script won't create a settings backup, so not a good idea for this issue, IMO.
