from-source ebook-edit errors on Plasma

[Eli Schwartz]

Using my from-source build of calibre, I get the following error when
trying to merge two files in ebook-edit:

calibre 2.76.0.r32.g392217d4 embedded-python: False is64bit: False
Linux-4.8.15-2-ck-i686-with-glibc2.0 Linux ('32bit', 'ELF')
('Linux', '4.8.15-2-ck', '#1 SMP PREEMPT Mon Dec 26 12:57:49 EST 2016')
Python 2.7.13
Linux: ('', '', '')
Traceback (most recent call last):

    raise AbortError('The master file (%s) must be one of the files
being merged' % master)
AbortError: The master file (OEBPS/&Text/TitlePage.xhtml) must be one of
the files being merged

The error occurs exclusively on Plasma, switching back to Cinnamon
everything works fine.
The prebuilt calibre binaries *also* work fine, even on Plasma!

Possibly some sort of weird Qt bug? Plasma occasionally freaks out in Qt
applications that other WM/DEs are okay with...

Up-to-date Arch Linux, so that means:
plasma 5.8.5
qt5 5.7.1

I have duplicated this bug from here: https://bugs.archlinux.org/task/52313

Fixed in branch master. The fix will be in the next release. calibre is usually released every Friday.
