Bug ID: 390865
Summary: Sometimes Crash When Performing Curve Fitting
Product: LabPlot2
Version: 2.4.0
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: alexander.se...@web.de
Reporter: tyna...@gmail.com
Target Milestone: ---
Application: labplot2 (2.4.0)
Qt Version: 5.9.3
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-32-generic x86_64
Distribution: KDE neon User Edition 5.12
-- Information about the crash:
I was repeatedly performing curve fitting with multi-peak Gaussian curves. The
algorithm for determining best fit doesn't work very well, so I have to
manually adjust values to be sorta close and then it seems to work.
Sometimes, however, it just crashes when I finish editing the curve parameters
and apply them. I sadly cannot remember now if it crashed when I hit 'Apply',
or if it crashed when I clicked the button to recalculate the curves.
There are a number of oddities to the version of Labplot2 in the Neon
repositories, though. It reports itself as version 2.4, but has a feature that
the website claims will be new in 2.5 (setting lower/upper limits on curve
fitting parameters).
I am using the 'User Edition' of KDE Neon, installed somewhat shortly before
Plasma 5.12 was released. I remember people saying that the LTS User Edition
got the 5.12 update sooner than the 'regular' User Edition, but now there is
only a single User Edition on the website - so I do not know how relevant this
information might be.
The crash can be reproduced sometimes.
