QComicBook

Hello,
I'm investigating missing files and it seems linked to qcomicbook.

Some important files have recently disappeared from my /home structure (I'm talking hundreds of files).
Instead plenty of directories qcomic-123456789 have appeared (8 to 10 random digits), all dated to the first time I installed and used qcomicbook:

$ find -name qcomic-\* | wc -l
87

$ ll -d $(find -name qcomic-\*)
drwxr-xr-x 3 dargaud dargaud 4096 janv. 5 21:58 ./Corono/OTHER/qcomic-1793889537/
drwxr-xr-x 2 dargaud dargaud 12288 janv. 5 21:58 ./Dargaud/MISC/qcomic-1364805944/
drwxr-xr-x 6 dargaud dargaud 4096 janv. 5 21:58 ./Dargaud/MISC/qcomic-2097758587/
drwxr-xr-x 5 dargaud dargaud 4096 janv. 5 21:58 ./Dargaud/MISC/qcomic-906977449/
drwxr-xr-x 3 dargaud dargaud 4096 janv. 5 21:58 ./Dargaud/qcomic-354961753/
...
drwxr-xr-x 3 dargaud dargaud 4096 janv. 5 21:59 ./Dargaud/WebPageStuff/Websites/Various/qcomic-670492322/


Most of those contain the same file names:

$ ls ./Dargaud/Text/Antarctic/qcomic-121457687/
Configurations2 content.xml META-INF meta.xml mimetype settings.xml styles.xml Thumbnails

But some contain random files from other directories (either copies or moved):

$ ls ./Text/MOUNTAIN/qcomic-67738215
Guil154.tif GUIL155.TIF GUIL156.TIF GUIL157.TIF Guil84.tif GUIL85.TIF GUIL86.TIF GUIL87.TIF GUIL88.TIF

The above files are from a zip files that is GONE. It's still in my backup so I'm sure of it.

Now some of those are directories I haven't touched in years. Not even 'cd' inside.
And now all those qcomic dir appear at the time I did use qcomicbook to read a few .cbz on an nfs share. They are all dated Jan 5, same two times one hour apart.


It's a new PC with a fresh install of Kubuntu and smartctl reports no error.

ALL my openoffice odt files are GONE. Instead I find traces of them in the form of xml garbage in the qcomicbook directories. For example:

$ grep contester Dargaud/Text/Misc/qcomic-330375409/content.xml
Je souhaite contester la pr
$ odt2txt BACKUP/Dargaud/Text/Misc/MISSING_FROM_HOME.odt | grep contester
Je souhaite contester la pr


Questions:
- does qcomicbook indeed create those qcomic-123456789 directories ?
- does it explore /home to find zip files and open them ?
- if so, how come they show up in so many old directories where I certainly have not opened it ?



My last backup is over a month old and there are so many differences that it's a fucking nightmare. I want to know if qcomicbook is responsible for this and what happened.
