Bug ID: 356887
Summary: crash during auto conversion of valid (previous
version) project
Product: kdenlive
Version: unspecified
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: alex.k...@gmx.de
openSUSE Leap 42.1 kdenlive 15.12
crash on clipitem.cpp:762 caused by fact that for all my projects in line 755
m_binClip->audioFrameCache is empty!
Reproducible: Always
Steps to Reproduce:
1. have an older version project
2. open it with new 15.12 version
3. after a long period of time kdenlive window just disappears
Actual Results:
Backup file is created but useless. The original project file is not really
converted.
Expected Results:
The project is converted and can be edited with new version
Program received signal SIGSEGV, Segmentation fault.

2: channels = 2

I cannot explain why a cache is empty. What is strange, that conversion process
prints almost endless sequence of ...

etc.
What is scary, the message box about creation backup and segmentation is not
synchronized with conversion process. As the crash happens, the last printed
message talks something about "Creating audio thumbnails (27/92)".
Probably cache creation process is not complete and object does not reference
the cache at all?
